It can't be done, in general. If you're talking about a line of your pygtk program, then you would need an API for your IDE (development environment) to find out where a particular source code line is currently displayed on the screen, if anywhere. If by "line number" you mean something else, then as Ignacio says, you'll need to provide a lot more detail.

I have a application written in PyGtk. I need to convert a particular line number into its corresponding window co-ordinates in a GtkTextView. How can this be done?

This kind of information is hard, very very hard to find information about. I am attempting to find the same but for Ruby, however I expect that the same issue will occur. Ultimately, however, a Manifest file is required, and at least during development, it may help to register the .dll anyway, and then work on making it registration free (with a manifest file)

I am currently using the win32com module of CPython to use a DLL. I know some people using IronPython to automagically get the list of functions provided by this DLL. They don't need to register the DLL. I'd like to do the same as them but with CPython. 1) Is it possible to use CPython and win32com to connect to a dll reg-free. How to make it reg-free? 2) How to get the list of functions provided by the DLL? I'd like to create a CPython module providing the whole list of functions. Any idea?

I'm not sure I understood exactly on the server side, but i'm a big fan of Flex as a way to develop proper software for the browser, rather than mess of trying to make HTML do things it was never made for. Partly an idealistic reasoning, but I also am still not impressed by the 'feel' of JS-based GUIs. Flex has good server-communication options... web-services, sockets, remote objects, etc.

Doing this in Python should be pretty trivial. It's probably possible in awk, but sounds a bit too complicated to be fun. It's surely is possible in bash, but programming in bash is for masochists. I'd go with Python, of the given options, although Perl and Ruby are good options too if you know them.

I have a set of 10000 files c1.dat ... c10000.dat. Each of these files contains a line which starts with @ and contains a string with spaces specific for this file, lije c37 7.379 6.23. I have another set of 10000 files kind of determined_cXXX_send.dat (where XXX goes from 1 to 10000). Each of these files has only one line. Each line is of thsis type: _1 1 3456.000000 -21 0 -98.112830 -20.326192 What I would like to do is, for each number XXX (between 1 to 10000), get from the cXXX.dat file the string like c37 7.379 6.23 , and add it in the file determined_cXXX_send.dat to the beginning of the file so I get: c37 7.379 6.23 _1 1 3456.000000 -21 0 -98.112830 -20.326192 I tried with both bash and python but got no good solution. What would be the best approach? thanks

I've never used PyFacebook. Or tried to resume sessions in this manner. But I'd imagine just storing session_key and uid is not enough. There are other params too, and a signature param that's calculated based on all the fb_* params. So you might need to store all of them. But even so, they might only work for 20-30 minutes if you're unlucky.

I am trying to set a cron task to read updates for a Facebook application. I have prompted the user to grant Offline Access permissions and i have store the session_key in the db. I am crearing a new Facebook object and besides api and secret key I also use the session_key (previously stored in db) and the fb uid. When i am trying to create the auth token or do a API call i get a Error 104: Incorrect signature Any ideas, experience, hints ?

PyQt installation also depends on the version of python installed on your platform.Python3.+ is incompatible with Python version < 3.x. I was facing the same problem as I have Python 2.7 installed on my machine but I downloaded the latest binary which was PyQt-Py3.2-x86-gpl-4.9.exe. If you see here the binary has python version also mentioned in name after PyQt which is Py3.2. I uninstalled PyQt and installed PyQt-Py2.7-x86-gpl-4.9.exe which points to Python 2.7 and it fixed the problem. Probably they could have mentioned the naming convention online or in some documentation to be more simpler.

I've been trying to install PyQt 4.7 on Vista, but I am getting an ImportError when I try to do: from PyQt4 import QtCore, QtGui. ImportError: DLL load failed: The specified module could not be found. I've checked my System Path, and C:\Python31\Lib\site-packages\PyQt4\bin is on there. I can't run any of the examples, but the Designer, Assistant and Linguist run fine. I am using ActivePython 3.1, if that makes any difference. And I haven't had any previous version of PyQt installed. Edit: I've copied the QtCore4 and GtGui4 dlls to C:\Python31\Lib\site-packages\PyQt4. That fixes some of the examples, but I still can't use the example browser.

Just wanted to chime in that I had the same problem on a WinXP install of: python 2.7 Qt 4.7.1 (10.05) PyQt 4.8.1 I used the windows installer version of all 3 of those items. Copying the contents of the C:\Python27\Lib\site-packages\PyQt4\bin folder up to the main PyQt folder (C:\Python27\Lib\site-packages\PyQt4) stopped the 'dll not found' errors that python was throwing.

I think there are at least two possible error conditions 1. ImportError: DLL load failed: The specified module could not be found. then you have to check your PyQT version is comptible with your python. In other words, if you use python 3.3, then you can only use PyQT for python3.3 and python 3.3 will not work with PyQT for python3.4 This was the problem I met. I solved it with re-install it 2. Import Error: DLL load failed: %1 then something strange on a different encoding Win32. then it would be a OS problem. If you use 32bit Python then you have to use 32bit PyQt, so do 64bit

I had the same problem. I got my program running from within Eclipse but when I tried running it directly from the command line I still got the same error. I solved it by renaming the C:\Users\Me\AppData\Roaming\Python\Python27\site-packages\PyQt4 directory. (I'm guessing leftovers from a previous PyQt install) I am using ActivePython.

Also chiming in. I installed both python 2.6 and PyQt 4.8.3 on a Windows 7 machine using the windows installers (I did NOT run 'python setup.py install'). I tried to run spyder (which requires PyQt 4.4 or greater) and failed because it couldn't find the PyQt .dlls. I copied all the .dlls from the \Lib\site-packages\PyQt4\bin folder to the \Lib\site-packages\PyQt4 folder, and spyder launches just fine.

How can I convert a .wav file to some other format such as .mp3 in pygame? Update: Why not Gstreamer or Pygame: I want to use native Windows environment to install a package that can do this (i.e. don't want to install cygwin). I am searching for a package which has a binary installer available for windows (with Python 2.6) or atleast where I can do "python setup.py install" without a need to install any dependencies.

Depends on what operations you're doing. Well, combine that with a general Python documentation, and that's about what you have. No. Again, depends on what you're doing. If you're only going to run a query once, no point in preparing it separately. If you are using persistent connections, it might. But they get cleared out whenever a connection is closed. Not likely. Sandboxing is broken in Python and AFAIK nobody is really interested in fixing it. I heard someone say that python-on-parrot may be the most viable way, once we have pl/parrot (which we don't yet). Bottom line though - if your stored procedures are going to do database work, use pl/pgsql. Only use pl/python if you are going to do non-database stuff, such as talking to external libraries.

we are still pretty new to Postgres and came from Microsoft Sql Server. We are wanting to write some stored procedures now. Well, after struggling to get something more complicated than a hello world to work in pl/pgsql, we decided it's better if we are going to learn a new language we might as well learn Python because we got the same query working in it in about 15 minutes(note, none of us actually know python). So I have some questions about it in comparison to pl/psql. Is pl/Pythonu slower than pl/pgsql? Is there any kind of "good" reference for how to write good stored procedures using it? Five short pages in the Postgres documentation doesn't really tell us enough. What about query preparation? Should it always be used? If we use the SD and GD arrays for a lot of query plans, will it ever get too full or have a negative impact on the server? Will it automatically delete old values if it gets too full? Is there any hope of it becoming a trusted language? Also, our stored procedure usage is extremely light. Right now we only have 4, but we are still trying to convert little bits of code over from Sql Server specific syntax(such as variables, which can't be used in Postgres outside of stored procedures)

I'm making a game which uses procedurally generated levels, and when I'm testing I'll often want to reproduce a level. Right now I haven't made any way to save the levels, but I thought a simpler solution would be to just reuse the seed used by Python's random module. However I've tried using both random.seed() and random.setstate() and neither seem to reliably reproduce results. Oddly, I'll sometimes get the same level a few times in a row if I reuse a seed, but it's never completely 100% reliable. Should I just save the level normally (as a file containing its information)? Edit: Thanks for the help everyone. It turns out that my problem came from the fact that I was randomly selecting sprites from groups in Pygame, which are retrieved in unordered dictionary views. I altered my code to avoid using Pygame's sprite groups for that part and it works perfectly now.

Best would be to create a levelRandom class with a data slot for every randomly produced result when generating a level. Then separate the random-generation code from the level-construction code. When you want a new level, first generate a new levelRandom object, then hand that object to the level-generator to produce your level. Later, to get the same level again, you can just reuse the levelRandom instance.

If you're using Hadoop Streaming, your input can be in any line-based format; your mapper and reducer input comes from sys.stdin, which you read any way you want. You don't need to use the default tab-deliminated fields (although in my experience, one format should be used among all tasks for consistency when possible). However, with the default splitter and partitioner, you cannot control how your input and output is partitioned or sorted, so you your mappers and reducers must decide whether any particular line is a header line or a data line using only that line - they won't know the original file boundaries. You may be able to specify a partitioner which lets a mapper assume that the first input line is the first line in a file, or even move away from a line-based format. This was hard to do the last time I tried with Streaming, and in my opinion mapper and reducer tasks should be input agnostic for efficiency and reusability - it's best to think of a stream of input records, rather than keeping track of file boundaries. Another option with Streaming is to ship header information in a separate file, which is included with your data. It will be available to your mappers and reducers in their working directories. One idea would be to associate each line with the appropriate header information in an inital task, perhaps by using three fields per line instead of two, rather than associating them by file. In general, try and treat the input as a stream and don't rely on file boundaries, input size, or order. All of these restrictions can be implemented, but at the cost of complexity. If you do need to implement them, do so at the beginning or end of your task chain. If you're using Jython or SWIG, you may have other options, but I found those harder to work with than Streaming.

I'm using Hadoop for data processing with python, what file format should be used? I have project with a substantial amount of text pages. Each text file has some header information that I need to preserve during the processing; however, I don't want the headers to interfere with the clustering algorithms. I'm using python on Hadoop (or is there a sub package better suited?) How should I format my text files, and store those text files in Hadoop for processing?

You don't say in your question what you are going to use Python for, so most answers above are completely correct in pointing out that you install Python by downloading it from Python.org. But you seem to expect more. Is it correct to assume you are going to use it to do web development? In that case, prepare for a shock, because Python doesn't do things like PHP does at all. You want to use a web framework. There are loads of them for Python. Which on to use depends both on what you are going to do, and your personal taste. The only "Download as one file and install to run" web system I know of that's based on Python is Plone. And Plone is great, but it's not a webframework, it's a content management system. But hey, maybe that's what you want? :-) The other frameworks are usually easy to install as well. (In the long run: If you are going to do web development, you'll be happier with something Unix based. Just saying.)

It uses Anjuta as its IDE, but I could never make sense of the entire compilation toolchain. However, I would like to know if Moblin could compile and run Python scripts.

I assume you mean 'idle' time. There is no need to calculate that, but you have to store the last (authenticated) access made by that user and reset the counter. Typically, one would should issue an authentication cookie with a certain timestamp. Upon authentication of the cookie, you compare the current time with the timestamp. If this difference is larger than some threshold, say 5 minutes, you present an error page. To improve the user experience, you might also want to display a timer to the user so there is no bad surprise.

I would like to have my PHP website destroy a users session if they have been idle for 5 minutes. If this does happen, I'd like to present the user with a message stating why they were logged out and redirect them to the login page. What is the best way to handle this? I am running on php and myadmin. Thanks Avinash

Can you not just use PHP's built-in session functions to set session expiry time to 5 mins. and re-direct if a session no longer exists?

Every time you load a page, store a timestamp in a session variable. When the user goes to a page, check to see if $SESSION['lastActivity'] < time() - <your idle time>. If true, then redirect to a 'your session has expired' page or similar. If not, continue loading the page.

Create a javascript function that has a x minute timeout that pops up and redirects. Also on the server make sure their session expires so that in the case of Javascript not being available, they cannot continue actions after their idle time has passed.

I have had to do this before (in .NET) and you are basically going to have to host a browser, get it to click the button, and then interrogate the DOM (document object model) of the browser to get at the generated HTML. This is definitely one of the downsides to web apps moving towards an Ajax/Javascript approach to generating HTML client-side.

I need to scrape a site with python. I obtain the source html code with the urlib module, but I need to scrape also some html code that is generated by a javascript function (which is included in the html source). What this functions does "in" the site is that when you press a button it outputs some html code. How can I "press" this button with python code? Can scrapy help me? I captured the POST request with firebug but when I try to pass it on the url I get a 403 error. Any suggestions?

Although you got what is probably a perfectly reasonable answer, there is another approach - you don't need to use asyncore's loop per se. Just call asyncore.loop with a zero timeout and a count of 1, which stops it iterating (and thus makes the function name completely misleading) and polls the sockets just once. Call this as often as you need. I don't know anything about glib's async support but if it requires threads you might still get better performance by using asyncore in this way since it will use select or poll and won't need to spawn additional threads.

just considering starting to learning python but I have one concern before I invest more time. Let me phrase this as a statement followed by a concern for others to comment on as perhaps the assumptions in the statement are invalid: I have read about GIL and the consensus seems to be if you require concurrent solutions in python your best bet is to fork a new process to avoid GIL. My concern is that if I have a problem I'd like to split into N*2 pieces across N processors (assume for example I have a single server running a *nix o/s with say 8 cores) I will incur context switching penalties between processes rather than between threads, which is more costly, which will limit performance. I ask this because other languages are out there that claim to excel in such a scenario and I wonder is python appropriate for this arena.

If you're considering learning Python for addressing this problem, I might suggest taking a look at Erlang instead. It has excellent support for very lightweight processes, and built-in primitives for IPC. Not to discourage you from learning Python, of course, just suggesting there might be a better tool for this particular task.

In my limited experience, the "context switch cost" is overrated as a performance limitation. I/O bandwidth and memory are the most common limiting factors. Python's I/O is comparable to many other languages, since it simply uses the standard C libraries pretty directly. Your actual problem may not be typical. However, many problems work out really well in multi-processing mode because they're actually I/O bound. Often it's filesystem, web page reading or Database operations that limit performance long before context switches.

As far as points #1 and #2 go, you are probably right. No other platform is so widely, easily and cheaply available in terms of hosting companies and packages like the LAMP stack. Plus, most incompatibilities that can occur when deploying an application to a completely unknown web space are well documented, their number is limited, and can mostly be checked beforehand (register_globals, safe mode, allocated script memory, etc.) If I were thinking about developing a web application that I want to see spreading as quickly and as far as possible also among non-professionals and end users, PHP would be my platform of choice for these reasons. I must add that I am deeply familiar only with the hosting market in Germany, but I'm quite sure the basic characteristics are the same. As for developer availability: People who claim to be able to speak PHP are easy to find. Those who will actually do a good job for you, less so. Still, I think it is safe to say that PHP developers are easier to find than, say, Pythonists or Ruby developers. I don't expect this to stay this way forever, though. Other languages are gaining popularity, and in the end, developers and which languages they like influences the hosting market massively in the long term.

My own answer to this question is YES, but I'd like to hear from others. Put another way the question could be: Would the success of 1-click-install WordPress (not WordPress.com, which is SaaS) be possible if it weren't written in PHP, all other things being equal? The critical associated requirements I believe support PHP are: hosting/deployment flexibility developer reach flexibility and depth of knowledge around server performance tuning Items #1 and #2 are equally critical, and both are far more important than #3. FWIW, I'm not a particular fan of PHP - can anyone truly be? - but the goals of re-deployment and extensibility point wherever they point. Please, please do not pollute this space if you do not grok the question. This is not about PHP and it's relative merits, or lack of merit, compared to other programming languages out of context. I am looking for insight specifically around language choice as it relates to deployment/uptake/extensibility strategy as outlined. Thanks.

Is PHP the only choice re: massive and rapid uptake of a re-deployable, extensible web application?

The answer to my immediate question in the headline is yes, with mechanize.Browser.open_novisit(). It works just like open(), but it doesn't change the state of the Browser instance -- that is, it will retrieve the page, and your Browser object will stay where it was.

In Python's mechanize.Browser module, when you submit a form the browser instance goes to that page. For this one request, I don't want that; I want it just to stay on the page it's currently on and give me the response in another object (for looping purposes). Anyone know a quick to do this? EDIT: Hmm, so I have this kind of working with ClientForm.HTMLForm.click(), which returns a urllib2 request, but I need the cookies from mechanize's cookiejar to be used on my urllib2.urlopen request. Is there a method in mechanize that will let me send a request just like urllib2 with the exception that cookies will be imported?

Can I get my instance of mechanize.Browser to stay on the same page after calling b.form.submit()?

I am looking for a linked list and related algorithms implementation for Python. Everyone I ask just recommends using built in Python lists, but performance measurements indicate that list insertion and removal is a bottleneck for our application. It's trivial to implement a simple linked list, but I wonder if there is a mature library which includes some operations like sort, merge, splice, search, lower/upper bound, etc... I know this is a dupe, but searching for python list on any search engine gives predictably poor results, with most people just saying that linked lists are unneeded in python (pfft!). PS: I need to insert and remove from anywhere in the list, not just the ends. OK, you asked for it: I need to maintain an ordered list of several hundred thousand entries. I will iterate over the list forwards (one by one), using a visitor on each entry, starting from the beginning or a position found by a binary search. When an entry matching a predicate is found it is removed from the list, and then, another binary search is performed on a subset of the list beginning from the removed entry's previous position, until a position determined statistically beforehand. Ignoring the error condition, the modified entry may be used to create another linked list which is spliced into the new position found through the second binary search. Iteration is continued from the position where the entry was removed. On occasion, several thousand contiguous ordered entries may be added to/removed from any place in the list. Sometimes several thousand non-contiguous entries must be searched for and removed incrementally. python's list is unnacceptable as the cost of insertion/removal is prohibitive, and the minor gains in speed for the binary search are totally irrelevant to the total cost. Our in house tests confirm this. if I have neglected any detail perhaps I can e-mail you a copy of my company's non-disclosure agreement and I can privately correspond with you on the matter. sarcasm.end().

For large data， keep a sorted list is a trick. Don't insert but append new items at the end and then sort it. Don't delet item but replace with a special value, sort them to the end and then pop out. For finding, a sorted list also has very quick performance with bisection method. As for small data, iterate old list， filter and build a new one, like list comprehensions method, is always the fast way. For me, what is large data? it should be over 1000000 items...

The protocol you described addresses one attack, that is the a replay attack. However, you are very vulnerable to MITM attacks. The TCP connection won't drop when the attacker moves in on the protocol. Further more anything transferred over this system can be sniffed. If you are on the wireless at a cafe everyone in the area will be able to sniff everything that is transmitted and then MITM the authenticated session. Another point is that sha1() is proven to be insecure you should use sha256 for anything security related. NEVER REINVENT THE WHEEL, especially when it comes to security. Use SSL! Everyone uses SSL and it has a LONG history of proven secuirty, and that is something you can't build. SSL Not only solved Man in the Middle Attacks but you can also use Certificates instead of passwords to authenticate both client and server which makes you immune to brute force. The sun will burn out before an attacker can brute force a 2048bit RSA certificate. Father more you don't have to worry about an eve dropper sniffing the transmission. Keep in mind that OpenSSL is FREE, generating certificates is FREE, and the singing of certificates is FREE. Although the only reason why you would want to sign a certificate is if you want to implement a PKI, which is probably not necessary. The client can have the server's public key hard coded to verify the connection. The server could have a database of client public keys. This system would be self contained and not require OCSP or CRL or any other part of a Public Key Infrastructure.

I wasn't sure how to phrase this question, so apologies in advance if it's a duplicate of something else. I wanted to sanity check how I've secured my twisted based application and think I've done a good job at it, but it's been over a decade since I've written anything that uses raw or managed sockets. Authentication transaction: Client connects and immediately a challenge response is sent back with a 16 character hex string. Client side takes user name & password, password is converted sha1( salt + sha1(password)) and credentials are sent back to the server as { username, password }. On the server side, authentication does standard lookup pattern ( if user exists and has password equal to input then grant ). If the connection between user & client is lost, the protocol class marks itself as dirty and disconnects itself from the user object. Any time after this point, to get access to the user object again, the client would have to repeat the authentication process with a new salt. Am I missing something? Is there a better/more secure approach for a character stream based protocol?

You've problably solved the problem already, but I just stumbled over the same problem with the Whoosh backend. Maybe the Xapian and Whoosh backends behave the same? Seems Whoosh is stemming all CharFields by default, and searching inside them with some kind of contains-query. Switching to a custom backend, without stemming enabled on CharFields, fixed this issue for me. Hopefully this will push someone else in the right direction.

So far I've been using CherryPy, and compared to Django (which, while not in your list, is the only other dev server I used) I like it heaps more. It does what is says: it is only there when you need it, and gets out of the way for the rest of the time. Using Django seemed like I needed to subscribe to the Django way of doing things. Although Django provides heaps more functionality out of the box (default admin interface, widgets on your webpages) , using CherryPy seems like just another import that has very good (often surprising you with extra) functionality.

explain better your problem, what operations and what elements you're focusing? regarding the problem with the elements beeing chosen more often, give each string an "chance multiplier", each comparison you multiply a number between 1 and 10 and the chance multiplyer of the string, if the result is higher than X (say... 5), so it select the string, if not, it searches for another string. this way, strings with higher multipliers will have more chance to be selected

Python strings are immutable, which means that they do not support item or slice assignment. You'll have to build a new string using i.e. someString[:3] + 'a' + someString[4:] or some other suitable approach.

In new enough pythons you can also use the builtin bytearray type, which is mutable. See the stdlib documentation. But "new enough" here means 2.6 or up, so that's not necessarily an option. In older pythons you have to create a fresh str as mentioned above, since those are immutable. That's usually the most readable approach, but sometimes using a different kind of mutable sequence (like a list of characters, or possibly an array.array) makes sense. array.array is a bit clunky though, and usually avoided.

While you can do this for classes defined in python code (it will not work for builtin ones) by reassigning their attributes please do not actually do so. Just subclass and use the subclass, or write functions that take an instance of the class as argument instead of adding your own methods. Doing what you have to mind leads to awkward, fragile code, especially if you end up using multiple libraries simultaneously that try to do this to the same classes. Is there an actual problem you're trying to solve this way?

Can access AppEngine SDK sites via local ip-address when localhost works just fine and a MacOSX using the GoogleAppEngineLauncher. I'm trying to setup facebook development site (using a dyndns.org hostname pointing at my firewall which redirects the call to my mac book). It seems like GoogleAppEngineLauncher defaults to localhost and blocks access to the ip-address directly. Is there a way to change that behaviour in GoogleAppEngineLauncher? Is this some kind of limitation built in by Google? It doesn't seem to be an issue of configuration, because there isn't any settings for this. So I'm guessing patching the source will be required?

Alex is right, start with the docs, and figure out which corpus reader will work for your corpus. The simple instantiate it, given the path to your corpus file(s). As you'll see in the docs, the builtin corpora are simply instances of particular corpus reader classes. Look thru the code in the nltk.corpus package should be helpful as well.

Came to understand how corpus reading works by looking at the source code in nltk.corpus and then looking at the corpora (located in /home/[user]/nltk_data/corpora/names - this will probably be in My Documents for XP and somewhere in User for Win7 users). The structure of the corpus and its related function will give a good understanding of how to use the different corpora available in NLTK. In my case I looked at the names variable in nltk.corpus' source code and was interested in the WordListCorpusReader function as the names corpus is simply a list of words.

Here is the situation: I have a Mediawiki installation, and a few additional server-side scripts that require more resources and were already written in a different language (python). The python code will be very loosely coupled with the Mediawiki code (only called by clicking on a link here or there) What I would like is that when a GET or POST command is sent to the server to execute a python script, I would like to check to see if a user is already logged in to Mediawiki. If not, I would like to just redirect them to the Mediawiki login page. Any ideas? There are several articles on integrating Mediawiki with other PHP frameworks like Drupal and forum software, but that is more than I need. What is the best way to do this? -check for cookies somehow (is this secure?) -does the Mediawiki database keep track of who is logged in? Thanks

I assumed that my python C module can access pygame stuff directly in C. Is this the case? No, that stuff is most likely just there because it was necessary to compile the pygame Python extension. I don't understand what you mean when you say you see 2 pygame instances. There are as many instances as you create, no more, no less. If you have script that creates pygame objects, and your extension also creates pygame objects, then of course you will have 2 sets of objects. As the writer of the application you need to decide which part of it will have responsibility for interfacing with pygame. If the other part requires access to those pygame objects, then you pass them in as arguments.

In my Python2_6/include directory is a folder with pygame headers. I assumed that my python C module can access pygame stuff directly in C. Is this the case? How do I integrate a C module that wants to use pygame, with a python script using pygame? Right now my brain sees: pygame <-- MyCModule <-- MyScript --> pygame ie. Two pygame instances. So is it possible to integrate them so that my module and my app use the same instance? Why are there pygame headers in my python include directory, can I use those somehow, for direct access? Thanks for any help.

I'm building a simple app, a sort of project/tasks manager where I can have several projects and several tasks that are assigned to one project. I enabled Django admin for all this sort of tasks and it's working like a charm. Also, I have some users that have projects assigned to them. So what I want now is to enable a cut down version of the admin for those users, where: They can only manage/see tasks within their own project. They can only delete their own tasks some other minor restrictions. What would be the best approach to this? Should I create another app with custom views and pages for client editing tasks or should I drop another admin instance and fine-tune it just for them? I hope it was clear and not too subjective. Thanks.

I know Ctrl + F9 runs a single file. How to run them all? If there is no such thing, how to bind one keyboard shortcut to it?

What is the keyboard shortcut to run all unit tests in the current project in PyDev + Eclipse?

Numpy is not supported on python 2.5 for Windows 64 bits, you need at least python 2.6, and even in that case, you need to build it by yourself, or use something like EPD or the installer given in link given by thor. NumPy cannot be used in Google App Engine, so I am not sure to understand the argument there.

I am using Python 2.6.4. I have a series of select statements in a text file and I need to extract the field names from each select query. This would be easy if some of the fields didn't use nested functions like to_char() etc. Given select statement fields that could have several nested parenthese like "ltrim(rtrim(to_char(base_field_name, format))) renamed_field_name," or the simple case of just "base_field_name" as a field, is it possible to use Python's re module to write a regex to extract base_field_name? If so, what would the regex look like?

I have a django-mingus blog running perfectly fine with the integrated development web server of django. It's installed in a virtualenv. Once deployed using the django app wizard of cherokee 0.99.42 the admin pannel is displaying a strange behaviour. Sometimes all apps are displayed in the admin pannel sometime only a subset of the apps are displayed. It's always the same apps that disapear from the main admin view. The manage.py runfcgi command is launched through the python interpreter installed in the virtualenv. Do you have a method to track that kind of problem ? Could it be related to environment variable that are not set correctly ? EDIT: Could this be a circular import problem ? 2nd EDIT: The same problem occur with nginx. Adding Debug=True to the ./manage.py runfcgi command make the setup stable.

You're going to need Objective-C: that's what all the tutorials, documentation, sample code, and everything is written in. In addition to a wilder variety of people being able to help you. So learn ObjC first. If, on your second or third project, or a year down the road, you start a project that needs a Python module (like, say, Twisted, or SQLAlchemy. But a SERIOUS need like foundation of your app need, where the extra boost your app gets makes everything worth it), then you can write a PyObjC app and get a lot of the speed benefits of that language, with your background in Cocoa.

Second class citizen seems a bit strong. The Objective-C API's are available from Python as well, should you need them, and that's mostly if you want to make Cocoa apps. But then they are restricted to OS X anyway. Personally, I have no interest in building apps that isn't cross-platform, but that's me. That also means I haven't actually done this, so I don't know how tricky it is, but there was an article in the Python Magazine not long ago, and it didn't look that horrible. The major drawback of Python is execution time, and that mainly comes from it being a dynamic language. This can be solved with Cython and C-extensions, etc, but then you get a mix of Python + ObjectiveC API's + Cython which can be daunting. So it depends a lot of what kinds of applications you are going to make. Something uniquely OSX-ish that makes no sense anywhere else? ObjectiveC is probably the ticket. Cross-platform servers, well then Python rocks! Something else? Then it depends.

DO NOT ATTEMPT to avoid learning objective-C if you're going to write apps for the Mac. The purpose of PyObjC and the other language bindings is to let you re-use existing libraries in your apps, not to let you avoid learning the native tools.

I have not used Django with Jython, so I can't speak to that specific issue, but I've used Jython for other things and I've found it quite stable of late, and just as easy as plain Python. I believe the "core committers" in Jython are substantially fewer than in C-Python (maybe 1/3 the number or less), if that's what you mean by "developer community", but I'm not quite sure what's the point in asking about this -- are you considering joining either developer community (Jython or Core Python) and wondering where you could have the best impact? If that's the case, I think the key issue isn't really how many others are already helping out, but, "what do you bring to the party" -- if you're a JVM wizard, or an expert at any important Java framework, you could be a real boon to the Jython community while that same skill would help much less in the C-Python community; vice versa, if you're a wizard, say, with autoconfigure and C-coded system calls, that would be precious for the C-Python community, but not as useful for the Jython community.

Well...you can pull it from the pmap application by calling pmap -x. But I was looking more for a way to access the info directly in /proc from my app. The only way to do it is to access the /proc/<pid>/xmap file. Unfortunately, the data is stored as an array of prxmap structs...so either a Python C-module is in order or using the ctypes module. I'll post an update when I get one of those written.

From the code in Antimony's answers it is easy to see that random.random() never returns exactly 1.0 on platforms that have at least 53 bit mantissa for calculations involving constants not annotated with 'f' in C. That's the precision IEEE 754 prescribes and is standard today. However, on platforms with lower precision, for example if Python is compiled with -fsingle-precision-constant for use on an embedded platform, adding b to a*67108864.0 can result in rounding up to 2^53 if b is close enough to 2^26 and this would mean that 1.0 is returned. Note that this happens regardless of what precision Python's PyFloat_FromDouble function uses. One way to test for this would be to check a few hundred random numbers whether the 53rd bit is ever 1. If it is 1 at least once this proofs sufficient precision and you are fine. If not, rounding is the most likely explanation meaning that random.random() can return 1.0. It's of course possible that you were just unlucky. You can push the certainty as high as you want by testing more numbers.

If your problem is that peaks remain for over one thousand generations, then the problem might not be with the crossover and mutation operators. You might not be introducing or keeping enough variation to your population: I would examine the proportions of crossovers, of mutations, and of survivors from one generation to the next, and possibly raise the proportion of mutations.

I'm working on webapp which has client-side UI coded in Flex 3 and backend is Pylons app. Our client communicates with backend using HTTP GET and POST requests, POST request bodies and all response bodies carry data in JSON format. Works well, just few gotchas: Flex apps cannot do PUT and DELETE requests. We work around this by doing POST requests and specifying the "real" intended method in X-HTTP-Method-Override header. Then we have some extra routes in routing configuration that handle these requests and treat them as normal PUTs and GETs. Flex apps can send custom HTTP headers but cannot read custom headers received from server (well they can on IE, but cannot on Firefox and Chrome, IIRC).

The difference between range() and xrange() is that the first returns the entire list, while the second returns a generator that generates each number as it is needed. The second one should work for any number, no matter how large. In Python 3.0, xrange() has disappeared and range() behaves like xrange() did previously.

It has two purposes: Anybody who reads the source will know what the exposed public API is. It doesn't prevent them from poking around in private declarations, but does provide a good warning not to.
