On your dev machine, use your browser to display the web page, and then save the 'result' with an appropriate file name/in an output directory. Thus, if you had mainfile.html which executed various time/last-mod directives and which included fileA.inc and fileB.inc at appropriate places, the resulting display (and save-able HTML file) will comprise all four/five components. =dn

I am developing the front end code of a website which I will be handing over to some developers for them to integrate it with the backend. The site will be written in .NET but I'm developing the front end code with static HTML files (and a bit of javascript). Because the header, footer and a few other elements are the same across all pages I am using Server Side Includes in my development environment. However, every time I hand the code to the developers I need to manually replace each SSI with the actual HTML by copying and pasting. This is starting to get tedious. I have tried writing a bash script to do this but my bash knowledge is extremely limited so I have failed miserably (I'm not really sure where to start). What I tried to achieve was: Loop through all the HTML files in my project Look for an include (  ) If one is found, replace the include with the HTML from the file specified in the include Keep doing this until there are no more includes and move on to the next file Does anyone know of a script that can do this, or can point me in the right direction for achieving this myself? I'm happy for it to be in any language as long as I can run it on my Mac. Thanks. EDIT It is safe to assume that all instances of  are on their own line.

I need a script that searches files for SSI and replaces the include with the actual HTML

Don't know if it is global or local (project-related). Globally you can set the interpreter via the path Window-Menu → Preferences → PyDev → Interpreter - Python. Project-related this can be done via right-click on project → Properties → PyDev - Interpreter/Grammar. Have a look at both and make sure that both are set to correct values.

After forced restart due to frozen laptop (windows 7 pro, 32 bit) Eclipse is providing the following message: It seems that the Python interpreter is not currently configured. How do you want to proceed?" Clicking the Auto config option and then ok I get the Python Interpreters window with the right name (Python), Location (c:\Program Files\Python27\python.exe) and system libs. It all looks ok but clicking OK or Apply doesn't seem to do anything and the whole thing starts from the beginning (the message about Python not currently configured...). I've checked my .pydevproject permissions and I have full control over the file. I also have dropbox sync-ing the project files but it has been ok for a while now. What is wrong, what should I check/do?

You need to follow the below steps. nltk.txt needs to present at the root folder Add the modules you want to download like punkt, stopwords as separate row items Change the line ending from windows to UNIX Changing the line ending is a very important step. Can be easily done through Sublime Text or Notepad++. In Sublime Text, it can done from the View menu, then Line Endings. Hope this helps

I have recently moved from Python on Windows to Python on Ubuntu. In Windows I could just hit F5 in the IDLE editor to run the script. However, in Ubuntu I have to run the script by typing python /path/to/file.py to execute. The thing is it seems the imports within the file are not working when I run from command line. It gives me the error: NameError: global name 'open_file' is not defined This is the open_file method of Pytables. In the python file I have: from tables import * I have made the file executable and all. Appreciate your help.

During a heavy operation a wx frame is "stuck" waiting on the process to finish. You're best solution is to create a worker thread and let it do the heavy job for you.

I have built a csv reader with. It iterats through a file and gives results based on search terms. I am reading 3 gig files. When I let it iterate through the file it works fine. But if I even touch the wxpython window after processing has begun the app stops responding then crashes. My best guess is I have to somehow monitor/throttle cpu usage. I have no idea how to do this or if I am on the right path.

OK, at the beginning I put the fields behind the encryption in a packet, and do all the encryption magic in post_build (encrypt) and pre_dissect (decrypt), but that was really tricky... so Instead I created another packet (EncryptedPacket) which overloads addfield and getfield to do all the encryption stuff, this solution is much cleaner and nicer then the previous one. I will add examples later.

I need to host multiple Django sites (quite a lot of sites actually) and currently I am using Apache+mod_wsgi but I want to switch to uWSGI. One of the nice features of uWSGI is cheaper mode that spawns processes as needed and shuts them down as needed as well. On the other hand, it seems that the way to make it run multiple sites is to use emperor mode. Can emperor mode be used together with cheaper subsystem? Are there any quirks/problems I should be aware of? Has anyone ever done this?

Is it possible to use both cheaper and emperor with uWSGI

I'm running celery and celery flower with redis as a broker. Everything boots up correctly, the worker can find jobs from redis, and the celery worker completes the jobs successfully. The issue I'm having is the Broker tab in the celery flower web UI doesn't show any of the information from Redis. I know the Redis url is correct, because it's the same URL that celeryd is using. I also know that the celery queue has information in it, because I can manually confirm that via redis-cli. I'm wondering if celery flower is trying to monitor a different queue in the Broker tab? I don't see any settings in the flower documentation to override or confirm. I'm happy to provide additional information upon request, but I'm not certain what is relevant.

I have a directed graph in which I want to efficiently find a list of all K-th order neighbors of a node. K-th order neighbors are defined as all nodes which can be reached from the node in question in exactly K hops. I looked at networkx and the only function relevant was neighbors. However, this just returns the order 1 neighbors. For higher order, we need to iterate to determine the full set. I believe there should be a more efficient way of accessing K-th order neighbors in networkx. Is there a function which efficiently returns the K-th order neighbors, without incrementally building the set? EDIT: In case there exist other graph libraries in Python which might be useful here, please do mention those.

If the problem is indeed to create a new password, I explain how to do it, but no code: Use the random.SystemRandom() if you want secure passwords. First create N characters from the set of allowed characters, where N is the length of your password. Then check if there are at least 2 digits. If there are less than 2 digits characters then remove 1 or 2 non-digit characters and add random digits, so that there are at least those 2 digits. Finally use the shuffle() to permute your password. That way your password has maximum entropy possible.

I've been trying to make a password creator to create a password for a assessment and one of the things that's needed is if the password doesn't have at least 2 numbers in it will print a error asking for a password with at least two numbers. I do not know how to do this and I was just wondering if you could give me a little hint on how I could do this in code. Thanks in advance

In the API it would be calling mfnTransform.setRotatePivotTranslation and setScalePivotTranslation with 'balance' turned on. There's not enough overhead to warrant a workaround - it's hard to see how this could be a bottleneck.

Is there a way to center the pivot of an object without the use of xform? I really would like to try and find a pyMel version of this, or the maya api, as xform is generally 10x slower than a pymel or api solution. Obviously you can achieve it with xform like so: xform(obj, cp=1) But I'm trying to find another way, does anyone know anything?

Python newbiew here. Please bear with me. Having written some good chunk of code one thing bothers me is that I cannot find a way to tell eclipse that this file/funciton is the starting point for my project (test). I step into code during debugging and end up in some file deep in the code. Then if I want to run it again I go to the tab containing the start file and run it again. It would be nice to be able to specify a "main" function for a python project like we do in C for e.g. Is something like that possible? If not can I at least tell eclipse to use that one file as the starting point for the project?

I am new here, but I will try to share my own experience with ES. Here, we are using couchDB to store the json we are indexing into ES. However, we do heavy modifications on those docs, like creating new nodes, etc etc. The docs are big, hundreds of fields, more than 15 nested collections. Finally, there are thousands of docs. So, yes, in my humble opinion, if you can create your docs via your application, I do not see why ES would have trouble with that. For the python part, though, I cannot help, we're doing things in java, here. However, for ES, I would use the bulk api. ES is (much, much) more efficient that way. I'd probably store the ids of the docs that couldn't be indexed due to random errors in another index (or in a file, or somewhere else) so that you can reconstruct and reindex them afterward, instead of a retry on error. (Though I couldn't know about the feasibility in python) not use a replica for an index currently indexing. For the retry on errors, I have mixed feelings. If the error is due to a wrong construction of the doc or to a mapping error, it will fail on each retry. Here, we are indexing thousands of those docs a minute, and still can issue search and facet requests (those could be slightly slower, though). This is not much, but I hope it helps. Good luck.

I am looking at the possibility of using ES without a database, constructing my data from my python application and sending it straight to ES in real time. It says me a lot of complexity, however my concern is that I might be generating data very quickly and sending requests relentlessly, even when ES might not be ready to accept it. My question is, in this case does it makes sense to use a queue system as a buffer between the two, so my application sends everything to a queue, and then queue tries to add it to ES, retrying if it doesn't have success. I am not sure if this is the most logical or efficient method. If anyone has any information or ideas on what queue systems would be suited, or if I even need one, I'd be very interested to hear.

I would definitely suggest a webapp. And the answer to your questions are given below: How would I receive and send notifications over a local network. Use a REST based web service to communicate with the server. You have to use polling to receive data:-( How could I connect to the server using NSURLConnection if it does not have a static ip? If possible configure a domain name in your network which points to server ip. (Configure local DHCP to give same IP to your server every time based on mac address!) Have a IP Range and when the app starts, try to reach a specific URL and check if it is responding. Ask the user to enter the server IP every time the app starts!

Background: I am just about to start development on an mobile and desktop app. They will both be connected to a local wifi network (no internet connection) and will need to communicate with one another. At the outset we are targeting iOS and Windows as the two platforms, with the intention of adding Linux, OSX, and Android support in that order. The desktop app will largely be a database server/notification center for receiving updates from the iOS apps and sending out the data to other iOS apps. There may be a front end to the desktop app, but we could also incorporate it into the iOS app if needed. For the moment we just want the iOS app to automatically detect when it is on the same network as the server and then display the data that is sent by that server (bonjour like). As far as I see it there are two paths we could take to implement this Create a completely native app for each platform (Windows, Linux, OSX). Pro: We like the ideas of having native apps for performance and ease of install. Con: I know absolutely nothing about Windows or Linux development. Create an app that is built using web technologies (probably python) and create an easy to use installer that will create a local server out of the desktop machine which the mobile apps can communicate with. Pro: Most of the development would be cross-platform and the installer should be easy enough to port. Con: If we do want to add a front-end to the server app it will not be platform native and would be using a css+html+javascript GUI. Question: My question is how would implement the connection between the iOS app and server app in each circumstance. How would I receive and send notifications over a local network. How could I connect to the server using NSURLConnection if it does not have a static ip? I hope this is clear. If not please ask and I will clarify. Update 09/06/2013 Hopefully this will clear things up. I need to have a desktop app that will manage a database, this app will connect to iOS devices on a local wireless network that is not connected to the internet. I can do this with either the http protocol (preferably with a flask app) or by using a direct socket connection between the apps and the server. My question is which of the above two choices is best? My preference would be for a web-based app using Python+Flask, but I would have no idea how to connect the iOS app to a flask app running on a local network with out a static ip. Any advice on this would be appreciated.

I'm trying to use the GCS client library with my app engine app and I ran into this - "In order to use the client library in your app, put the /src/cloudstorage directory in your sys.path so Python can find it." First, does this mean I need to move the directory into my sys.path OR does it need to add the ~/src/cloudstorage/ to my PATH environment variable? Second, when I print sys.version and sys.path from the App Engine Interactive Console, I see a Python Version of 2.7.2, but when I print from my Terminal (on a Mac), I get the Python I want to use and installed via Homebrew - 2.7.5. The sys.path in the Console shows all App Engine paths and the default Python installation - /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7 On my terminal - /usr/local/Cellar/python/2.7.5/Frameworks/Python.framework/Versions/2.7/ I need help understanding how to change this. ** UPDATE ** Okay, I figured out part of this answer. "In order to use the client library in your app, put the /src/cloudstorage directory in your sys.path so Python can find it." means moving the actual directory to the App Engine project directory. The second piece still remains - why is my Mac PATH environment variable not used in APP Engine. How can I change the default version of Python used by the App Engine (from 2.7.2 to 2.7.5)? This is not related to changing the version in the YAML file.

sendevent takes 4 parameters args for Popen should be ['adb', 'shell', 'sendevent /dev/input/eventX type code value'] - do not split the remote command timings are important for sendevent sequences and adb shell call itself is kind of expensive - so using shell script on the device works better pay attention to the newline characters in your shell scripts - make sure it's unix style (single \n instead of the \r\n)

I am running into a strange issue, running adb shell sendevent x x x commands from commandline works fine, but when I use any of the following: subprocess.Popen(['adb', 'shell', 'sendevent', 'x', 'x','x']) subprocess.Popen('adb shell sendevent x x x', shell=True) subprocess.call(['adb', 'shell', 'sendevent', 'x', 'x','x']) They all fail - the simulated touch even that works in a shell script does not work properly when called through python. Furthermore I tried adb push the shell script to the device, and using adb shell /system/sh /sdcard/script.sh I was able to run it successfully, but when I try to run that commandline through python, the script fails. What's even stranger, is that he script runs, but for example, it does not seem to execute the command sleep 1 half way through the script, echo commands work, sendevent commands don't seem to work. Doesn't even seem possible, but there it is. How do I run a set of adb shell sendevent x x x commands through python?

DragonFly uses the shared recognizer, which starts Windows Speech Recognition. If you modify DragonFly to use an inproc recognizer, Windows Speech Recognition will not start. (Unfortunately, I don't know enough Python to contribute a fix.)

Context I'm working with DragonFly, the python module. At this point, I just want speech recognized and outputted back to me. Question I'm wondering if there is a way to use DragonFly purely for voice recognition without going through Windows Speech Recognition (or any alternative program). Is Dragonfly only meant for "post-speech-recognition"? The examples I've seen and run all open up windows speech recognition. I've also looked into the old speech recognition module - pySpeech, but that also "borrows" windows speech recognition. Should I be looking towards other modules?

DragonFly - no external application?

Prepare a dictionary to store the results. Get the numbers of line with data you have using xlrd, then iterate over each of them. For each state code, if it's not in the dict, you create it also as a dict. Then you check if the entry you read on the second column exists within the state key on your results dict. 4.1 If it does not, you'll create it also as a dict, and add the number found on the second column as a key to this dict, with a value of one. 4.2 If it does, just increment the value for that key (+1). Once it has finished looping, your result dict will have the count for each individual entry on each individual state.

I'm using the python packages xlrd and xlwt to read and write from excel spreadsheets using python. I can't figure out how to write the code to solve my problem though. So my data consists of a column of state abbreviations and a column of numbers, 1 through 7. There are about 200-300 entries per state, and i want to figure out how many ones, twos, threes, and so on exist for each state. I'm struggling with what method I'd use to figure this out. normally i would post the code i already have but i don't even know where to begin.

Some contras of using Firebase: Your data is in an external server (deal-breaker for sensitive data) It costs money You have an additional dependency that you don't fully control (if they go out of service/business you might be in trouble) You know the pros. If you think these are not relevant to you then go for it.

Since Firebase can do user login as well as hold a lot of other stuff about users and their interactions with my app. What are some of the advantages and disadvantages of using Firebase solely as a web framework, instead of using django, pyramids, bottle, etc etc? http routing, etc etc.... I have that sorta stuff handle by another process... So, if I'm looking basically to hold some user stuff and allow for user logins and user to user private/personal communications. It seems firebase is an almost total solution, no? I know this isn't a technical question, but I'm just looking for opinions from a realtime crowd....stackoverflow seems the best fit.

i've written a few unittests for a Django project. I'd like to debug them. I've set a break point on the server side. what should I click to run the Django unittest with debugging enabled in PyDev Eclipse? It seems I can run the manage.py test command from Pydev, but then there's no debugging. If I run the unittest with right-click debug unittest, then I get all sort Internal Server errors presumably because the test envrionment wasnt set up correctly.

The use of in and not in is not enough to produce correct results unless you limit input to only one use of "ie" or, if not only one use, only one usage (type of use). There seems to be an attempt to analyze words in isolation, but the above is valid for words too. The program needs to either use a RegEx (with a look-behind) or scan the text properly. To answer your question, the "index out of range error" occurs because line2 is a split of line1, which is constant "Line: ". This means that line2 is always equal to ["Line:"]. On the second iteration of the while, a takes the value 1, which is an invalid index for line2. If you add if a >= 1: break before any use in the loop of line2[a], this exception will not occur any more. Now, for the reasons I expressed above, I don't think the program is going to accomplish its stated objectives anyways.

Pip should be installed when you create the virtual environment. Don't change directory into C:\Python33\Scripts before running pip. It looks like that means you use the base install's pip instead of your virtual environment's pip. You should be able to run pip from any other directory. However I'm not familiar with python on Windows, so I'm not certain that pip is added to the path when you activate the environment. If that doesn't work, you'll have to change directory into the bin directory of your virtual environment, then run pip.

You have many questions, I'll try to respond to them one by one. If you have a service that uses a specific port, and you have multiple computers on the same ip addess, how is this handled? Someone mentioned that multiple computers cannot have the same IP address. In the original IP model, this is true, though today such address sharing (through NAT) is common. But even in the original model, your question makes sense if you reformulate it slightly: "If you have a service that uses a specific port, and you have multiple clients on the same ip address, how is this handled?" There can be multiple client processes on the same host (thus sharing the same IP address) trying to contact the same server (using the same destination address+port combination). This was natural at the time IP was developed, as most machines powerful enough to connect to the network were multi-user machines. That's why TCP (and UDP) have port numbers on both sides (source and destination, or client and server). Client processes typically don't specify the source port when contacting a server, but an "ephemeral" source port is allocated to the socket by the host operating system for the lifetime of the socket (connection). So this is how the server distinguishes between clients from the same address: by their source ports. NAT maps different hosts (with different "internal" IP addresses) to the same "external" IP addresses, but it also allocates unique source ports to outgoing packets. So the server sees this just like the original case (multiple client processes from the same "host"/IP address). The NAT then "demultiplexes" the server's responses to the different internal hosts. Should the service specify to which computer on the ip address the information should be send? What if both computers on the same ip use the same service, but request different information? The server does this by sending responses to the same address+port combination that the different clients used as source address/port. This is mostly handled automatically by the socket API. As described above, the two clients will get separate connections, and the server hopefully handles these as separate "sessions" and doesn't confuse requests between these sessions. Also, if a client is on a dynamic ip, how should the service detect that the ip has been changed, but the client (and the session) is the same? Should clients identify themselves for every request (much like cookies over http)? Now, this is a whole can of worms. If a service wants to "survive" client IP address changes, then it will have to use some other identifier. HTTP (session) cookies are a good example. TCP connections are broken by address changes - this is normal, as such changes weren't envisioned as part of normal operation when TCP/IP was designed. There have been attempts at making TCP/IP more robust against such changes, such as Mobile IP, MPTCP, and possibly SCTP, but none of these have really entered the mainstream yet. Basing your protocol on HTTP(S) and using session cookies may be your best bet.

I don't think I fully understand what you've said. There is no way that multiple computers will be on the same IP, this is not how the internet works.. There are protocols which hadels such things. Did you mean that you're a server and multiple computers try connect to you? If so, you listen in a port and when you get a connection you open a new thread for the service of that computer and the main loop still listening

Type: "C:\python\Lib\site-packages\PyQt5\pyuic5.bat" -x Trial.ui -o trial_gui.py for cases where PyQt5 is not a path variable. The path in quotes " " represents where the pyuic5.bat file is.

In settings, under the Project section (in the left pane) go to Interpreters. From there you can select a found environment or click the + to add your own from a path. Find the environment you created and add it to the list. Then, once you select the environment you can see the installed modules underneath. You can add new modules through their built in pip. After that, it'll take you to the first page where you have to select your custom environment from a drop down. Good luck! Edit: Reread your question. Sometimes when I can't get the module to be recognized in PyCharm, I do a pip install through the command line in the virtual environment. Then restart PyCharm. Navigate to the environment in cmd and run python -m pip install -U SOUNDCLOUD_MODULE and it'll work.

Greetings to everyone! I've got a little issue in a project made by someone in PyCharm, with virtual environment(VE) precisely. I've set this VE up few months ago and didn't use it for some time. Now i need to go back to it, because it has a lot of necessary things installed. Therefore there is one more battery needed to be installed into this VE - it is soundcloud API. I installed by directly from PyCharm in project settings, i checked whether this VE is still a default VE - it is. But project keeps complaining that there is "No module named soundcloud". Can you show me the way i can fix this? Thanks in advance.

Each hexadecimal digit carries 4 bits of information. You have eight hexadecimal digits. Therefore, the number carries 32 bits of information. It just happens that the address fits in 32 bits. If you are using a 32-bit Python, this will always be the case; if you are using a 64-bit Python, it could be that the address just happened to have all high bits zero and ended up fitting into 32 bits.

Hash functions are one way tickets. You cannot use them for encryption. Hash function algorithms are realised through modulo, xor and other familiar (one way) operations. You may try to find what argument was used to generate hash but in theory you will never be 100% sure it is the correct value. For example try with a really simple (useless in cryptography) hash function modulo 10. This function returns ten different values. If it's 7 you may guess the entry was 7 or 137 and 1234567. Same with md5, sha1 and better ones. As you can see, in the case when you are using hash function that returns only 40 bytes with files that are much bigger (maybe even few hundred megabytes) there in theory exists infinite numbers of files for each possible hash.

To find out what Com applications you can use... See http://timgolden.me.uk/pywin32-docs/html/com/win32com/HTML/QuickStartClientCom.html Basically you can't know for sure. Sorry. Each computer will have a different list based on the software installed, the webpage I linked suggests using pyWins ComBrowser, however I haven't ever found it that useful. My normal approach is 'I want to interface with application X in Python... lets google "python com X" and see what comes up' or 'I want to interface with application X in Python.. lets look through the documentation of AppX for references to COM' Afterall you'll want to have some form of documentation to that programmes COM interface in order to be able to do anything meaningful with the program (other than opening it).

self.pool.get is used to get the Singleton instance of the orm model from the registry pool for the database in use. self.browse is a method of the orm model to return a browse record. As a rough analogy, think of self.pool.get as getting a database cursor and self.browse as a sql select of a records by Id. Note if you pass a browse an integer you get a single browse record, if you pass a list of ids you get a list of browse records.

What's the difference between self.browse() and self.pool.get() in OpenERP development?

The codeless way to do this is to make use of Plone's workflow system. Out-of-the-box, Plone's file and image content types do not have their own workflow. That means that files and images will simply inherit the publication state of their parent folder. This is easy and sensible, but it doesn't meet the need you're describing. To change the situation, you may use the "types" configuration panel to turn on independent workflow for files and images. Then, their publication status may be set separately from their containing folders. Typically, you'd choose the same workflow that you're using for documents. Then, you may publish a folder and list its contents while having the files within be private -- thus requiring login for viewing. If you need this to work differently in different places, you may turn on "placeful" workflow (turn it on by adding it in the add-ons panel; it's pre-installed, but not active). This allows different workflows in different parts of a site. It increases complexity, but is often an ideal solution to this kind of puzzle.

I wish to make the contents of a folder in Plone downloadable only for certain roles. Can this be done easily? At present anybody who clicks the hyperlink for file name in the folder contents can download the file easily. I know about the site-wide option of overriding the at_download code using ZMI.

How do I make files downloadable for a particular role in Plone?

You need to analyze why your program is slowing down when other threads do their work. Assuming that the threads are doing CPU-intensive work, the slowdown is consistent with threads being serialized by the global interpreter lock. It is impossible to answer in detaile without knowing more about the nature of the work your threads are performing and of objects that must be shared in parallel. In general, you have two viable options: Use processes, typically through the multiprocessing module. The typical reasons why objects are not picklable is because they contain unpicklable state such as closures, open file handles, or other system resources. But pickle allows objects to implement methods like __getstate__ or __reduce__ which identify object's state, using the state to rebuild the objects. If your objects are unpicklable because they are huge, then you might need to write a C extension that stores them in shared memory or a memory-mapped file, and pickle only a key that identifies them in the shared memory. Use threads, finding ways to work around the GIL. If your computation is concentrated in several hot spots, you can move those hot spots to C, and release the GIL for the duration of the computation. For this to work, the computation must not refer to any Python objects, i.e. all data must be extracted from the objects while the GIL is held, and stored back into the Python world after the GIL has been reacquired.

I'm creating a simple multiplayer game in python. I have split the processes up using the default thread module in python. However I noticed that the program still slows down with the speed of other threads. I tried using the multiprocessing module but not all of my objects can be pickled. Is there an alternative to using the multiprocessing module for running simultaneous processes?

If the source is in .txt format regular expressions probably would be the best solution. I don't think it easy (or even possible) to write a regex for all arbitrary kinds of ads but the more examples you'll have the better your search will work.

There are a lot of classified ads appearing in NON-HTML format(paper ,text ,written ,etc) which tend to sell house,automobile,rent,lease,flat,etc. A classified ads say for example, a flat rent ad has some of the features included like: SIZE,AREA,LOCALITY,PRICE,CONTACT INFO. .etc My question is how to extract the street address(address mentioned in article /LOCALITY) in which the ad resides or has mentioned in former article ? Is there any solution to this problem using NLTK & python ?? Imagine that the source of article is in normal text file(.txt) .

You want os.path.split + os.path.splitext. Please take some time reading the doc next time, it would have been waaaayyyy faster than posting here.

I'm trying to separate a string into three variables where C:\Example\readme.txt could be read as C:\Example, readme, and .txt for the sake of a script I'm writing. It may be deployed in both Windows and Unix environments and may deal with both Windows or Unix paths, so I need to find a way that complies to both standards; I've read about several functions that achieve similar to this, but I'm looking for some input on how to best handle the single string inside a function. *Note, I'm running IronPython 2.6 in this environment, and I'm not sure if that varies so greatly with standard Python 2.7 that I would need to adapt my usage. EDIT: I'm aware of using os.path.splitext to get the extension from the filename, but finding a platform-independent way to get both the path and the filename (which I later use splitext on) is what boggles me.

What is the most stable and Pythonic cross-platform way to separate a string of path,filename,ext into three separate variables?

Each process has a separate instance of the global variable. If you want each process to see the same value, you'll need to pass that value as an argument to each process.

With this global variable defined in the script upper focus t0 = time.time() ## is global and this function def timestamp(t0): ... return ("[" + str(time.time()-t0)+ "] ") ## time stamping from initial start I'm trying to timestamp every print() of my script with print(timestamp(t0) + ""...whatever..."") This works, but when i'm enterring multithreading by for thread_id in range(win32-safe_os): ... p = Process(target=fonction, args=((thread_id),"test")) ... p.start() ... thread_list.append(p) in order to def fonction(thread_id,filetodo): ... print(timestamp(t0)+"Load core "+str(thread_id)) ... print(timestamp(t0)+str(filetodo)+" on core "+str(thread_id)) ... print(timestamp(t0)+"Free core "+str(thread_id)) i get this stdout : [2.70299983025] 297 jpg / 36087 files [2.75] Enterring multithreading [2.75] Win32 finds : 2 core(s) [0.0] Load core 0 [0.0] test on core 0 [0.0] Free core 0 [0.0] Load core 1 [0.0] test on core 1 [0.0] Free core 1 I can see that my call to timestamp() and t0 is working, but not in p.start(). I'm wondering how(, and why) i need to correct ? PS : I tried with time.clock, but in win32 it refers to the beginning of a THREAD (not a script)/

I'm probably going to write a Python script for this soon. I had written a reporting app before in C#, but it's badly written and I think Google has changed their API again so it's not working anymore. The way I did it was to use tags. I wanted my total work hours per client. I would enter them into Google Calendar as: @clientname description of work Where clientname can be the first few letters only and the software matches it to a full name from a list of clients. My software would then allow you to chose a time-period and one or more clients and would output them into a neat looking Word file. PS: to by honest the suggestion of using gtimereport.com seems very bad to me. You're basically uploading all of your calendars to strangers. That's why I'm going to write a script for this.

I am planning my all day activities in Google calendar LIke Offcie time sleeping playing Gym I am happy with Google but issue is that i don't get reporting so that i can see how much time is spent in each category. I know python and django so i was thinking is it possible that i still log all events in Google calendar and then i have daily cron jobs which will fetch events from Google calendar and then put in mysql database. The main issue is i want to define separate categories for different things. Like WORK, SLEEP, SHOPPING etc. But how can i do that from event name only. DO i need to enter some words in events whicg i can grab and make them as category. ANy ideas on that

Can i generate reporting using google calendar

It is possible to do the job with one pass and without loading the entire file into memory as well. Though the code itself is going to be much more complicated and mostly unneeded unless the file is HUGE. The trick is the following: Suppose we only need one random line, then first save first line into a variable, then for ith line, replace the currently with probability 1/i. Return the saved line when reaching end of file. For 10 random lines, then have an list of 10 element and do the process 10 times for each line in the file.

i have to basically make a program that take a user-input web address and parses html to find links . then stores all the links in another HTML file in a certain format. i only have access to builtin python modules (python 3) . im able to get the HTML code from the link using urllib.request and put that into a string. how would i actually go about extracting links from this string and putting them into a string array? also would it be possible to identify links (such as an image link / mp3 link) so i can put them into different arrays (then i could catagorize them when im creating the output file)

You haven't described many limitations, so I assume it's just a simple copy operation you're after. "Best way" is kinda vague, I don't know what you're comparing against. The only thing that you'd want to be careful about is to do the actual work of creating the new entity, copying data over, and deleting the old entity in a transaction. This is simple to do, and will prevent you from creating duplicates in case something goes wrong. The remote API shell is definitely the least-coding-effort way to do it. You can write simple python functions to do your transactional copy, and run it in the shell. You don't need to write any extra handlers, and you don't even need to deploy a new version of your app. The problem with the remote shell is that it's probably 100x slower in accessing your datastore, so it could take a long time. If you let it run overnight, it potentially could stop if you have a hiccup in your internet connection - though this shouldn't be a huge problem if you copied your entities in a transaction, you can just restart the operation. Just as a reference, I recently ran an operation via remote API that uploaded 6000 entities, it took maybe 5 minutes. If you're ok with letting the operation run overnight, this is probably the way to go unless you have > 100K entities. The mapreduce API method will run faster, since the load will be spread across a number of instances. A bit more effort to get mapreduce set up, and you'll have to deploy a new version of your app with the functionality, kick it off, wait until it finishes, and maybe clean out the code, as well as a bunch of logging entities that mapreduce automatically generates.

I have this script in python on linux which deploys vnc locally, does some graphical job on this vnc screen, and kills vnc. Sometimes after the job is done process named gnome-panel hangs and stays with 100% cpu usage. Then I need to log in through putty and kill all those processes manually (sometime lots of them actually). I would like to add few lines to my python script when it finishes its job, which will not only kill vnc (it does it already), but also kill gnome-panel if it consumes certain amount of cpu over given time period. I cant simply kill all gnome-panels, as some of them are working fine (im deploying 4 vnc screens at the same time). So I need this condition in python: if process name is gnome-panel and consumes over 80% of cpu and runs over 1 minute, kill process id thank you!

After some research and with the help of python-pptx's creator, I was able to write to the PowerPoint COM interface using a Virtual Machine. In case someone reads this thread, this is how I managed to get this done: - Setup a VM with Microsoft Windows/Office installed on it ; - Install Python, Django and win32com libraries on the VM. The files are sent locally from the original Django project to the virtual machine (which are on the same network) through a simple POST request. The file is converted on the VM using win32com.client (which is just a simple call to the win32com.client library) and then sent back as a response to the original Django view, which in turn processes the response. Note: it took me some time to realize I needed to use the @csrf_exempt decorator for this setup to work.

First of all, I agree that this might sound like a question which has already been asked many times in the past. However I couldn't find any answer that was relevant to me in the similar questions so I'll try to be more specific. I would need to transform PPTX/DOCX files into PDF using Python but I don't have any experience in file format conversion. I have been looking in many places/forums/websites, read a lot of documentation and came across some useful libraries (python-pptx and pyPdf mainly), but I still don't know where to start. When looking on the Internet, I can see many websites that offer file format conversions as a paying service, even with advanced API's: submit a file via POST and get the transformed PDF file in return. This could work for me, but I am really interested in writing myself the code that does the conversion work from OOXML to PDF. How would you start doing this? Or is it just impossible on my own? Thanks for your help!

I have a vector of pointers to objects in c++ and want to expose it to python with a list. So far I gave a reference of a python list to c++. I figured pointers are not suitable for python so I read about how to make a pointer to a reference by (*obj) it. But when I call: myList.append((*obj)); python just crashes. Can someone tell me how to put objects I only have pointers of into a python list correctly so I can manipulate that list later? Greetings Chris

MyISAM has no transactions, so you can't not to "autocommit" using MyISAM. Your runtime change may be also caused by the fact you moved from innoDB to MyISAM. The best approach for DB runtime issues in general is benchmarking, benchmarking and benchmarking.

I've been working with Python MySQLdb. With InnoDB tables autocommit is turned off in default and that was what I needed. But since I'm now working with MyISAM tables, the docs for MySQL say MyISAM tables effectively always operate in autocommit = 1 mode Since I'm running up to a few hundreds of queries a second, does committing with every single query slow down the performance of my script? Because I used to commit once every 1000 queries before, now I can't do that with MyISAM. If it slows it down, what can I try?

Just regarding the use of regular expressions: Regular expressions are equivalent to finite automatons and these have the property that they have only a finite set of states, which in turn means they have kind of finite memory. Thus you can't do stuff involving an unknown arbitrary lenght objective string.

I'm assuming you're paying a lot in instance hours. Reading from the GAE filesystem is rather slow. So the easiest way to optimize is only read from the static file once on your instance startup, keep the js file in memory (ie a global variable), and print it. Secondly, make sure your js is being cached by the customers so when they reload your page, you don't have to serve the js to them again unnecessarily. Next way is to serve the js file as a static file if possible. This would save you some money if the js file is big and you're consuming CPU cycles just printing it. In this case have your handler that generates the HTML insert the appropriate URL to the appropriate js file instead of regenerating the entire js each time. You'll save money because you won't get charged instance hours for files served as static files, plus they can get cached in the edge cache (GAE's CDN), and you won't get billed anything at all for them.

We have a piece of Javascript which is served to millions of browsers daily. In order to handle the load, we decided to go for Google App Engine. One particular thing about this piece of Javascript is that it is (very) slightly different per company using our service. So far we are handling this by serving everything through main.py which basically goes: - Read the JS static file and print it - Print custom code We do this on every load, and costs are starting to really add-up. Apart from having a static version of the file per customer, is there any other way that you could think about in order to reduce our bill? Would using memcache instead of reading a file reduce the price in any way? Thanks a lot.

_idletimer is likely to be a private, possibly implementation specific member of one of the classes - since you do not include the code or context I can not tell you which. In general anything that starts with an _ is private and if it is not your own, and specific to the local class, should not be used by your code as it may change or even disappear when you rely on it.

I am creating a GUI program using wxPython. I am also using matplotlib to graph some data. This data needs to be animated. To animate the data I am using the FuncAnimate function, which is part of the matplotlib package. When I first started to write my code I was using a PC, running windows 7. I did my initial testing on this computer and everything was working fine. However my program needs to be cross platform. So I began to run some test using a Mac. This is where I began to encounter an error. As I explained before, in my code I have to animate some data. I programmed it such that the user has the ability to play and pause the animation. Now when the user pauses the animation I get the following error: AttributeError: 'FigureCanvasWxAgg' object has no attribute '_idletimer'. Now I find this to be very strange because like I said I ran this same code on a PC and never got this error. I was wondering if anyone could explain to me what is meant by this _idletimer error and what are possible causes for this.

The Pythonic way to do it is not to care what platform you are on. If there are multiple different facilities to accomplish something depending on the platform, then abstract them behind a function or class, which should try a facility and move on to another if that facility is not available on the current platform.

I'm trying to determine if the operating system is Unix-based from a Python script. I can think of two ways to do this but both of them have disadvantages: Check if platform.system() is in a tuple such as ("Linux", "Darwin"). The problem with this is that I don't want to provide a list of every Unix-like system every made, in particular there are many *BSD varieties. Check if the function os.fchmod exists, as this function is only available on Unix. This doesn't seem like a clean or "Pythonic" way to do it.

How can I determine if the operating system a Python script is running on is Unix-like?

I am assuming you are talking about modules, which are a mean of collecting sets of features and/or custom data types. They exist to enrich the Python standard library, which already contains over 200 packages and modules (they can be listed by entering help('modules') in a Python interpreter. Modules are meant to be imported and used by your programs. As an FYI, modules that provide related functionality can be grouped together in a package. Pypi, the Python Index Package, is a repository of such third-party modules. Chances are you will find an existing module for whatever task you want to accomplish, just search Pypi for for interests you. You have two options to install them: Download and install them manually (here assuming the module is foo-1.0): gunzip -c foo-1.0.tar.gz | tar xf -# unpacks into directory foo-1.0 cd foo-1.0 python setup.py install Install them with pip in a virtualenv environment (virt_env)user@computer$ pip install SomePackage==1.0 The typical installation path on Unix/Linux is prefix/lib/pythonX.Y/site-packages, where prefix is by default /usr. On windows, it the install path is prefix\Lib\site-packages, where prefix is C:\Program Files\Python.

Sorry for such a basic question, I couldn't really find an answer through google that I could understand. What exactly is a python library in laymans terms? It seems like its something that you download or import and move into a certain folder to add a specific functionality in python? If I download a library for python, does it go in /usr/lib ? Any help would be appreciated I'm really lost on this!

Python libraries are called "modules". These modules provide commonly used functionality in the form of different objects or functions. For example, there is a module that has functions you can use in your code to test if files exist on your hard drive; there are modules that have functions for implementing web-server, or web-browser functionality; there are modules to work with images; there are modules to create charts and graphs; there are modules to parse XML or HTML files; etc. The idea is that there are things lots of people might want to do with python - e.g. read HTML files. Everyone could write python code to do that themselves, but that's time consuming. So smart people write a module that does this in a well-defined - and well-documented - way. Everyone else just has to import that module and use it. Then the low-level work (e.g. reading an HTML file) is done, and you just get to use the HTML file to do whatever clever work you want to do.

When i do tutorials like "Effective Django" they use the virtualenv command on an empty folder, then activate it. That works, until tomorrow when I want to work on the app again at which point the virtualenv is gone. I strongly doubt that this is the case, unless something is deleting your directories overnight. If that is the case, stop putting your code where it is being deleted. Assuming that is not the case, the solution is for you to go back to the directory you created as a virtualenv, and reactivate it.

Sorry if this is dumb but every piece of documentation i read doesn't ever seem to answer this question in a direct way. How do i properly use virtualenv so that I have a virtualenv i can call with workon? When i do tutorials like "Effective Django" they use the virtualenv command on an empty folder, then activate it. That works, until tomorrow when I want to work on the app again at which point the virtualenv is gone. What do i do at this point, I've used mkvirtualenv before and that creates a "permanent" virtualenv i can call with "workon" but I don't understand how i would use mkvirtualenv on an existing project or if this is a good idea or not, as it stands i have a project I virtualenv yesterday that has a bin folder in it and I am not sure if I need to source it again or what. Ideally i want to just workon project and get to work.

I can see /Library/Python through finder and on clicking Library/Python I see 2.3, 2.5, 2.6, 2.7. The default Python currently is 2.7which I can see with --version. But all it has is /site-packages. How is this possible? I am not sure if it is the one that came with the OS or if it was installed later by someone. I am so so confused. OSX 10.8.4

For me, the easiest and most convenient method to quickly lookup methods is the command helm-occur (C-x c M-s o). You start typing the name of the method you want to jump to and suggestions start popping in as you type. Then you hit enter to select the one you want and your cursor jumps right there in the code. Helm-occur wasn't strictly written for this purpose, but works quite well that way.

I like that IPython will fetch docstrings if I type foo.bar? However, I may sometimes build the foo.bar method dynamically, using foo.__getattr__. I could conceivably also generate a docstring dynamically, perhaps in a magic method like foo.__getdoc__. Does IPython provide any mechanism for doing this, such that it would discover and display docstrings built on the fly?

Is there a way to generate IPython docstrings on the fly?

No, I think that's built-in. You would have to catch the selection event and probably make all the cells editable so you could select just the cell. Otherwise I would look at UltimateListCtrl as that is a custom widget and you can probably subclass it in such a way as to add that functionality. Or don't use a ListCtrl at all and switch to using a wx.Grid

I don't know Mahout. But think about that: At least with JPype and Py4J you will have performance impact when converting types from Java to Python and vice versa. Try to minimize calls between the languages. Maybe it's an alternative for you to code a thin wrapper in Java that condenses many Javacalls to one python2java call.

After searching for an option to run Java code from Django application(python), I found out that Py4J is the best option for me. I tried Jython, JPype and Python subprocess and each of them have certain limitations: Jython. My app runs in python. JPype is buggy. You can start JVM just once after that it fails to start again. Python subprocess. Cannot pass Java object between Python and Java, because of regular console call. On Py4J web site is written: In terms of performance, Py4J has a bigger overhead than both of the previous solutions (Jython and JPype) because it relies on sockets, but if performance is critical to your application, accessing Java objects from Python programs might not be the best idea. In my application performance is critical, because I'm working with Machine learning framework Mahout. My question is: Will Mahout also run slower because of Py4J gateway server or this overhead just mean that invoking Java methods from Python functions is slower (in latter case performance of Mahout will not be a problem and I can use Py4J).

Experienced Django users seem to always err on the side of putting code in models. In part, that's because it's a lot easier to unit test models - they're usually pretty self-contained, whereas views touch both models and templates. Beyond that, I would just ask yourself if the code pertains to the model itself or whether it's specific to the way it's being accessed and presented in a given view. I don't entirely understand your example (I think you're going to have to post some code if you want more specific help), but everything you mention sounds to me like it belongs in the model. That is, creating a new Operation sounds like it's an inherent part of what it means to do something called add_operation()!

I'm pretty novice so I'll try to explain in a way that you can understand what I mean. I'm coding a simple application in Django to track cash operations, track amounts, etc. So I have an Account Model (with an amount field to track how many money is inside) and an Operation Model(with an amount field as well). I've created a model helper called Account.add_operation(amount). Here is my question: Should I include inside the code to create the new Operation inside Account.add_operation(amount) or should I do it in the Views? And, should I call the save() method in the models (for example at the end of Account.add_operation() or must it be called in the views?) What's the best approach, to have code inside the models or inside the views? Thanks for your attention and your patience.

The libpq driver, which is what the psycopg2 driver usually used by django is built on, does not support forking an active connection. I'm not sure if there might be another driver does not, but I would assume not - the protocol does not support multiplexing multiple sessions on the same connection. The proper solution to your problem is to make sure each forked processes uses its own database connection. The easiest way is usually to wait to open the connection until after the fork.

I have an application which receives data over a TCP connection and writes it to a postgres database. I then use a django web front end to provide a gui to this data. Since django provides useful database access methods my TCP receiver also uses the django models to write to the database. My issue is that I need to use a forked TCP server. Forking results in both child and parent processes sharing handles. I've read that Django does not support forking and indeed the shared database connections are causing problems e.g. these exceptions: DatabaseError: SSL error: decryption failed or bad record mac InterfaceError: connection already closed What is the best solution to make the forked TCP server work? Can I ensure the forked process uses its own database connection? Should I be looking at other modules for writing to the postgres database?

So one solution I found is to create a new thread to spawn from. Django opens a new connection per thread so spawning from a new thread ensures you pass a new connection to the new process. In retrospect I wish I'd used psycopg2 directly from the beginning rather than Django. Django is great for the web front end but not so great for a standalone app where all I'm using it for is the model layer. Using psycopg2 would have given be greater control over when to close and open connections. Not just because of the forking issue but also I found Django doesn't keep persistent postgres connections - something we should have better control of in 1.6 when released and should for my specific app give a huge performance gain. Also, in this type of application I found Django intentionally leaks - something that can be fixed with DEBUG set to False. Then again, I've written the app now :)

You just have to make an object of type vntProcessor, if this class exists, or import the module vntProcessor in the GUI module, so you can use its functions and process the data (path and subfolder list).

i am making an application that has GUI and some classes. I ran into a problem of getting an idea for the logic. here is a brief description of the program: Structure: 3 modules Module 1 - dataPreparation.py -responsible for string processing - made of several classes and methods that receive PATH to directory, collect all files in a LIST, after that for each file based on type of file name it sorts it out to appropriate categories that can be accessed through class instances. Module 2 - gui.py - Responsible for GUI. It crates a simple GUi-layout that offer BROWSE button (to get the PATH), QUIT button to exit application, LISTBOX that lists subfolders from the PATH, and BATCH button that must execute the main processor. Module 3 - vntProcessor.py - Responsible for processing of collected data. This module is based of an API of another application. It receives the values from the BATCH-button and invokes specific methods based on sorting that was performed using MODULE 1. So, here is the logic problem that i encountered, and i wanted to ask what is the best way to handle it. My approach: I crated scene7_vntAssembler.py . This file imports Module 1(dataSorting), Module 2(GUI), Module 3(Processor) i create an instance of GUI and call it to start interface ( have a window open) in the interface, i browse for specific folder, so my PATH variable is set. my list box is populated with subfolders. my next step should be to press the BATCH folder and forward all of the values (PATH and ARRAY of SUBFOLDERS) to my Module 3 (processor). Problem: I cannot figure out the way to do that. How to pass the PATH and SUBFOLDER-LIST to module 3? and invoke operations on collected data?

MySQL controls access to tables from its own list of users, so it's better to create MySQL users with permissions. You might want to create roles instead of users so you don't have as many to manage: an Admin, a read/write role, a read-only role, etc. A Django application always runs as the web server user. You could change that to "impersonate" an Ubuntu user, but what if that user is deleted? Leave it as "www-data" and manage the database role that way.

The company I work for is starting development of a Django business application that will use MySQL as the database engine. I'm looking for a way to keep from having database credentials stored in a plain-text config file. I'm coming from a Windows/IIS background where a vhost can impersonate an existing Windows/AD user, and then use those credentials to authenticate with MS SQL Server. As an example: If the Django application is running with apache2+mod_python on an Ubuntu server, would it be sane to add a "www-data" user to MySQL and then let MySQL verify the credentials using its PAM module? Hopefully some of that makes sense. Thanks in advance!

Can a Django application authenticate with MySQL using its linux user?

You can't save two forms in one .ui file, but I think that you can do this (I did not tried it but it should work): save for example one QDialog and one QMainWindow (QFrame can't stand alone-it needs parent widget) in separate .ui files, convert them via pyuic4 command to two .py files and then join those two files into one .py module (copy data from one to another - copy class and create instance in __main__). That is not very practical when you want to change something in designer , because you'll need to do whole procedure again.

The best way to solve this would be to have the sending process SFTP to a holding area, and then (presumably using SSH) execute a mv command to move the file from the holding area to the final destination area. Then, once the file appears in the destination area, your script knows that it is completely transferred.

I am using Python to develop an application that does the following: Monitors a particular directory and watches for file to be transferred to it. Once the file has finished its transfer, run some external program on the file. The main issue I have developing this application is knowing when the file has finished transferring. From what I know the file will be transferred via SFTP to a particular directory. How will Python know when the file has finished transferring? I know that I can use the st_size attribute from the object returned by os.stat(fileName) method. Are there more tools that I need to use to accomplish these goals?

This is not exclusive to wxPython and is not a bug. Try this in any Windows application and you will see you can save a txt file as a .exe in Notepad or open a .png file in MS Word. A file extension is just a convention, which means it can be broken for any number of reasons. If you are confident that you must check the file extension of a file, you will need to perform some validation with the return value of the wx.FileDialog.

1

I noticed that even if you set your wildcard to match *.txt files only, all wx.FileDialog does is list all txt files under that directory, still you can input any existent file with a different extension and hit open button without having any problem at all? There doesn't seem to exist a window style to avoid this from happening, so I guess you have to validate the file extension yourself, right? Interesting, does this count as a bug?

I hear that the permissions level via crontab and terminal is totally different. More specifically, my python script has a command to write a file into the /tmp/ directory. On a linux machine, everything works, both cron and regular shell. However on OSX, the terminal runs fine but when this command is set on the crontab, an error appears saying that we don't have permissions to write to the /tmp directory. How should I handle this? Thanks.

When the python interpreter is running a module (the source file) as the main program, it sets the special __name__ variable to have a value "__main__", not as main().

Also, why do we use the underscores? After all, I define the main method as main(), not as __main__().

Why using "if __name__=='__main__': main()" and not simply "main()" in Python?

I have alreay made a project like this. I have used one table with mixed languages, with a column to specify which language it is. I have no problem with this implementation. An other approach I had thought is to create dynamically a table like content_ and to fill in. But very boring (you have to manage id dependancy with other tables) and not necessary for me. Have you got a fixed number language ?

In my Django Project I am using the i18n internationalization to translate all templates. Now, depending on the chosen language I also would like to separate the data that users are submitting to the database. I do not want to have mixed languages in one table. What is the best approach how to solve this problem? I am developing using Django 1.5.2.

Extent defines the images max and min of the horizontal and vertical values. It takes four values like so: extent=[horizontal_min,horizontal_max,vertical_min,vertical_max].

Im wanting to use imshow() to create an image of a 2D histogram. However on several of the examples ive seen the 'extent' is defined. What does 'extent' actually do and how do you choose what values are appropriate?

What does extent do within imshow()?

If you're not using NDB, use NDB. Your data won't change, just the way you interface with the datastore will. NDB entities are automatically cached so any requests by key are searched for in memcache first and then the datastore if the entity is not found. NDB is the new standard anyways, so you might as well switch now instead of later.

I have several appengine entities that are frequently read at different places of my applications and not so frequently updated. I'd like to use memcache to reduce the number of datastore reads of my app, but i don't really want to update my code everywhere. I was wondering if there is a decent way to override the get() method of my entity to check if we stored it in memcache before doing a datastore read, and use put() to delete this memcache entry. Does someone have a good solution for that ?

Is there a efficient way to override get() and put() method in an appengine entity to make it use memcache?

I'm assuming you've solved the problem by now. If you haven't, you can now install pillow using brew by going brew install samueljohn/python/pillow. Why it isn't just brew install pillow is beyond me.

I'm attempting to install the Pillow fork of PIL, and every method I've tried results in this error: unable to execute /: Permission denied error: command '/' failed with exit status 1 This occurs using pip install Pillow using easy_install Pillow-master.zip using python setup.py install using python setup.py build The last is the most confusing to me, honestly. I can't even build the module in the same directory it's been extracted to. I've made sure to install all of the prereqs using homebrew, just as the Pillow readme suggests. This error has not occurred when installing other python modules. Edit: I have run all of these commands with and without sudo.

Yes. Plenty. Determine number of times to iterate. Start a random number generator. Set variable previous to None or similar. Start iteration. Generate next random number and compare it with previous. If it is the same, skip it.

I try to constantly show one of 5 possible items randomly (for a 100 times or so), BUT the important thing is that the SAME item is not allowed to be shown immediately after each other. There needs to be (at least) always one other item in between. Any idea? Thank you soo much

pick random item from a list with constantly reapeating items, but not repeat one twice immediately after

Note that DBSCAN doesn't actually need the distances. Look up Generalized DBSCAN: all it really uses is a "is a neighbor of" relationship. If you really need to incorporate uncertainty, look up the various DBSCAN variations and extensions that handle imprecise data explicitely. However, you may get pretty much the same results just by choosing a threshold for epsilon that is somewhat reasonable. There is room for choosing a larger epsilon that the one you deem adequate: if you want to use epsilon = 1km, and you assume your data is imprecise on the range of 100m, then use 1100m as epsilon instead.

I've been running sci-kit learn's DBSCAN implementation to cluster a set of geotagged photos by lat/long. For the most part, it works pretty well, but I came across a few instances that were puzzling. For instance, there were two sets of photos for which the user-entered text field specified that the photo was taken at Central Park, but the lat/longs for those photos were not clustered together. The photos themselves confirmed that they both sets of observations were from Central Park, but the lat/longs were in fact further apart than epsilon. After a little investigation, I discovered that the reason for this was because the lat/long geotags (which were generated from the phone's GPS) are pretty imprecise. When I looked at the location accuracy of each photo, I discovered that they ranged widely (I've seen a margin of error of up to 600 meters) and that when you take the location accuracy into account, these two sets of photos are within a nearby distance in terms of lat/long. Is there any way to account for margin of error in lat/long when you're doing DBSCAN? (Note: I'm not sure if this question is as articulate as it should be, so if there's anything I can do to make it more clear, please let me know.)

Python uses what is called "Duck Typing" i.e. if it looks like a duck and it sounds like a duck you might as well call it a duck. You can use: Parameter type checking, Parameter conversion, Exceptions & Documentation

I'm new to python, just have one question: Python don't need to declare variable types. For example, when we use functions, we don't declare which type should be passed in. So sometimes, I can't figure out which type the passed in parameter actually is or do I pass in an invalid parameter. For example, a parameter named: run_date, Its type can be string or datetime or date. I have to find it from the code... Is there a way to solve this problem? I think I should do good naming. But howto? I don't mean to check the type in the code. I just get confused with the function parameters when coding... I always forget which type the parameter is...

Be aware that control characters in response content could block the parsing of the xml and, for example, just cut data. At least this is what happened to me. Maybe I'm a little bit late, anyway I spent so much time today on this issue that I would like to share what I've finally found. At the beginning I've tried to check if there is some limits somewhere: in xml-rpc server php code, in my apache http server, in the python xml-rpc client (base on incution xml-rpc library)... but found nothing. Than I begun searching for hidden control characters in the response content and finally found a record separator ASCII character. Deleted and all worked well.

This is likely too general a question but, googlin' around for hours, I haven't found anything. I have a web application based on zope/plone/python where zope/plone is used, among other things, as a soap and xml-rpc web server. However sometimes (when response is "big") my xml-rpc response is truncated(*) as if the xml-rpc protocol could not handle more than "x" characters (or bytes). Is anyone aware of this? Bonus question: If you were in my shoes, what would you look for during "investigation"? I've also added "python" tag because zope/plone components are written in this language and, maybe, there are some pythoners that could help me. (*) Received to caller (that is onto another network, for example) truncated.

Does xml-rpc have some kind of "response length limit"?

The simplest way is write a script in python for them I guess... If you are running a Windows Server you can even schedule the comand that you use (scrapy crawl yoursprider) to run the spiders.

I have a set of Scrapy spiders. They need to be run daily from a desktop application. What is the simplest way (from user's point of view) to install and run it on another windows machine?

How do I package a Scrapy script into a standalone application?
