I am working on a project where I need to extract the Mel-Cepstral Frequency Coefficients (MFCC) from audio signals. The first step for this process is to read the audio file into Python. The audio files I have are stored in a .sph format. I am unable to find a method to read these files directly into Python. I would like to have the sampling rate, and a NumPy array with the data, similar to how wav read works. Since the audio files I will be dealing with are large in size, I would prefer not to convert to .wav format for reading. Could you please suggest a possible method to do so?

I am using pexpect with cgi to ssh into remote machine, Whenever i run a script which does ssh using pexpect from the linux terminal it gives me the correct result, but when i call the script using commands module from the cgi program i am getting the following error.

I just started setting up a centos server today and noticed that the default version of python on centos is set to 2.6.6. I want to use python 2.7 instead. I googled around and found that 2.6.6 is used by system tools such as YUM so I should not tamper with it. Then I opened up a terminal on my mac and found that I had python 2.6.8 and 2.7.5 and 3.3.3 installed. Sorry for the long story. In short I just want to know how to lookup all the version of python installed on centos so I don't accidentally install it twice.

As someone mentioned in a comment, you can use which python if it is supported by CentOS. Another command that could work is whereis python. In the event neither of these work, you can start the Python interpreter, and it will show you the version, or you could look in /usr/bin for the Python files (python, python3 etc).

I've seen other similar questions but none of the solutions are working for me. I am trying to get Twilio working with Google App Engine. I am using the python API and can't seem to get it to work. I tried a few tactics: used pip install twilio downloaded the twilio file directly into my root directory sym linked the required files according to a few tutorials nothing seems to work.

I am trying to convert a python script to an executable file. I have tried cxFreeze and py2exe, but both told me that Python27 are not in the registry. I found several other questions that tell me to go to regedit and find the python folder, but it is not there. I tried going to HKEY_CURRENT_USER/Software and Python27 was not there. Do I need to add it there to run the installer for cxFreeze or py2exe or is there another way?

I have a python program which posts to my local web server. The script runs on a raspberry pi running the latest version of raspbian 3.18. How can I make the Python script run at startup? Raspbian has a login password which is the first thing I have to remove. If the power ever goes out I want the pi to reboot and start running my script again. Should I be using Raspbian for this? The script is the only thing the pi is used for. I tried adding the script to /etc/init.d but I do not think it will run either way if the pi requires login info upon booting.

You can use the Linux crontab to run the Python script. Let's go to root and create a shell script. sudo -i nano startup.sh Then type your python script on this bash script. navigate to home directory, then to this directory, then execute python script, then back home. cd / cd home/pi/your directory sudo python yourpythonscript.py cd / Save the script and then exit. Make this sh script executable by giving it permission. chmod 755 startup.sh Now open and edit rc.local file. nano /etc/rc.local Add /root/startup.sh & before exit 0 now save and exit from the file and reboot your pi. sudo reboot

unittest.shortDescription() returns only the first line of the test method's docstring. Is there a way to change this behavior, e.g. to display the entirety of the docstring, or to display another message ? Would I need to override shortDescription() ? EDIT: I did know that shortDescription() takes no arguments (besides the implicit object reference), but I was very unclear in the wording of my question. What I'm really looking for is pointers to how to override shortDescription() and get at, say, the entire contents of the docstring. Thanks !

The landscape of Python tools that seem to accomplish the task of propagating Earth satellites/celestial bodies is confusing. Depending on what you're trying to do, PyEphem or Python-SGP4 may be more suitable. Which of these should I use if: I want ECEF/ECI coordinates of an Earth satellite I want general sky coordinates of a celestial object Near Earth vs. far away objects Want to use two-line element sets Do any of these accomplish precise orbit determination? If not, where do I go/what resources are there out there for precise orbit determination? I kind of know the answers here. For instance, POD is not part of any of these libraries. These computations seem to be very involved. POD for many objects are available from IGS. The main reason I ask is for documentation purposes. I'm not familiar with python-skyfield, but I have a hunch it accomplishes what these other two do. --Brandon Rhodes, I await your expertise :)

Michael mentioned it in his comment, but PyEphem I believe is deprecated as of the current Python 3 version. That being said, if you are to use TLEs, SGP4 was made to handle TLEs in particular. The non-keplerian and non-newtonian terms you see in TLEs are specifically passed into the SGP4 propagator (B* drag, second derivative of mean motion, etc.). Once you get outside of Earth neighborhood (beyond GEO), SGP4 is not meant to handle these cases. SGP4 in of itself is inherently a near-earth propagator that does not scale well on an inter-planetary or even cis-lunar regime. In fact, if you are to have both apogee and perigee extend beyond GEO, I would tend to avoid SGP4. It is important to note that SGP4 outputs things in a TEME frame (true equator mean equinox). This is an inertial frame. If you want ECEF coordinates, you will need to find a package that converts you from inertial to fixed frames. Regardless of whether or not you desired earth-fixed coordinates, I highly recommend making this conversion so you can then convert to your inertial frame of choice.

I want to create a python library with a 0 argument function that my custom Robot Framework keywords can call. It needs to know the absolute path of the file where the keyword is defined, and the name of the keyword. I know how to do something similar with test cases using the robot.libraries.BuiltIn library and the ${SUITE_SOURCE} and ${TEST NAME} variables, but I can't find anything similar for custom keywords. I don't care how complicated the answer is, maybe I have to dig into the guts of Robot Framework's internal classes and access that data somehow. Is there any way to do this?

I took a relatively quick look through the sources, and it seems that the execution context does have any reference to currently executing keyword. So, the only way I can think of resolving this is: Your library needs also to be a listener, since listeners get events when a keyword is started You need to go through robot.libraries.BuiltIn.EXECUTION_CONTEXT._kw_store.resources to find out which resource file contains the keyword currently executing. I did not do a POC, so I am not sure whether this actually doable, bu that's the solution that comes to my mind currently.

Sorry if the title is misleading. I am trying to write a program that calculates frequency of emails being sent out of different email ids. We need to trigger alerts based on number and frequency of mails sent. For example for a particular email if in past 60 minutes more than 25 mails were sent, a trigger needs to be sent. A different trigger for another directory based on another rule. Fundamental rules are about how many mails sent over past 60 minutes, 180 minutes, 12 hours and 24 hours. How do we come up with a strategy to calculate frequency and store it without too much of system/cpu/database overheads. The actual application is a legacy CRM system. We have no access to the Mail Server to hack something inside the Postfix or MTA. Moreover there are multiple domains involved, so any suggestion to do something on the mail server may not help. We have ofcourse access to every attempt to send a mail, and can look at recording them. My challenge is on a large campaign database writes would be frequent, and doing some real time number crunching resource intensive. I would like to avoid that and come up with an optimal solution Language would be Python, because CRM is also written using the same.

Try to do hack on client side in recording email attempt to a log file. Then you can read that file to count frequency of emails sent. I think that you can put data in memory in dict for some time say for ex 5 or 10 min. Then you can send data to DB thus not putting load on DB of frequent writes. If you put a check in your code for sudden surge in email from a particular domain then it might provide you a solution for your problem.

I was trying to build an encryption program in python 2.7. It would read the binary from a file and then use a key to encrypt it. However, I quickly ran into a problem. Files like image files and executables read as hex values. However, text files do not using open(). Even if i run file=open("myfile.txt", "rb") out=file.read() it still comes out as just text. I'm on windows 7, not linux which i think may make a difference. Is there any way i could read the binary from ANY file (including text files), not just image and executable files?

Your binary file is coming out looking like text because the file is being treated like it is encoded in an 8 bit encoding (ASCII or Latin-1, etc). Also, in Python 2, bytes and (text) characters are used interchangeably... i.e. a string is just an array of ASCII bytes. You should search the differences between python 2 and 3 text encoding and you will quickly see why anomalies such as you are encountering can develop. Most of the Python 2 version encryption modules use the python byte strings. Your "binary" non-text files are not really being treated any differently from the text ones; they just don't map to an intelligible coding that you recognize, whereas the text ones do.

There are so many options. 'Polling' is generally a bad idea, as it assumes CPU occupation. You could have your script send you status changes. You could have your script write it's actual status into a (remote) file (wither overwriting or appending to a log file) and you can look into that file. This is probably the easiest way. You can monitor the file with tail -f file over the link And many more - and more complicated - other options.

this is a conceptual question. As part hobby, part art project I'm looking to build a Python script that allows two people to play battleships between their computers (across the net, without being on the same network). The idea would be you could run the program something like: python battleships.py 192.168.1.1 Where the IP address would be the computer you wanted to do battle with. I have some modest Python coding abilities but I'm curious how hard it would be to build this and how one might go about it? One key goal is that it must require almost zero set-up: I'm hoping anyone can download the python script, open the terminal and play battleships with someone else. Thanks!

I'd like to be able to pay the users of my site using PayPal Mass Payment. I think this is pretty straightforward if they have a PayPal account. However, if they do not have a PayPal account, is there any way to have them sign up through my site, without leaving? Or just with a nice redirect? Whatever is least friction. I just don't want to lose users in the onboarding experience. This is analogous to Stripe managed accounts, but I'm not sure if PayPal has such an analogue.

PayPal doesn't have a way for people to sign up entirely through your site, although there are some ways to facilitate the process. You'd probably have to call PayPal to get access to some of those as they are aimed primarily at larger businesses. However, don't neglect the easy/automatic assistance that PayPal gives you: you can pay to any email account, and if that email is not already active on a PayPal account then the payment will be waiting for them when they activate that email into an existing or new PayPal account. So you can onboard merchants to your site and leave the PayPal signup for later, when money will be waiting for them to claim. Psychologically, walking away from money is harder than than deciding not to start processing :).

My project has existing (relatively low-coverage; maybe 50%, and a couple of them can't actually test the result, only that the process completes) tests using Python's built-in unittest suite. I've worked with hypothesis before and I'd like to use that as well - but I'm not sure I want to throw out the existing tests. Has anyone tried having two completely separate testing frameworks and test sets on a project? Is this a good idea, or is it going to cause unexpected problems down the line?

IMO, If current framework supports the attribute based categorization then you can separate them by adding separate categories to have separate results from old and new tests. On the other hand you can also go for multiple framework if they're supported and have no conflict of interest(E.g. asserts, test reports) by the test runner in your project. But in this case you'll end up having two separate reports from your test executions.

I have a set of unit tests files created in python with unittest as the import. Running nosetests on both the terminal of MacOSX and on the cmd.exe of Windows 7, it finds the tests and runs them. Trying to execute nosetests under Cygwin does not find any tests to run. All three cases use the same version of Python (3.4) and the same version of nose(1.3.6). Also, none of the files are marked as executable I suspect that is something environmental on cygwin. Does anyone know that do I need to do?

I have a very basic CGI based front end hosted on an IIS server. I'm trying to find the users within my shop that have accessed this site. All users on the network sign on with their LAN (Windows) credentials and the same session would be used to access the site. The python getpass module (obviously) returns only the server name so is there a way to find the user names of the visitors to the site? The stack is Python 2.7 on IIS 8.0, Windows Server 2012

When using Windows authentication on IIS, the server variables should contain the username in two variables: AUTH_USER and REMOTE_USER CGI offers access to all server variables, check your Python docs on how to access them.

I am looking for an efficient algorithm to find the longest run of zeros in a binary string. My implementation is in Python 2.7, but all I require is the idea of the algorithm. For example, given '0010011010000', the function should return 4.

I don't think there is anything better than a single pass over the string, counting the current sequence length (and updating the maximum) as you go along. If by "binary string" you mean raw bits, you can read them one byte at a time and extract the eight bits in there (using bit shifting or masking). That does not change the overall algorithm or its complexity.

I have a Python script which process data off of a HTTP data stream and I need this script to in theory be running at all times and forever unless I kill it off manually to update it and run it again. I was wondering what the best practice to do this was on a Unix (Ubuntu in particular) so that even if Terminal is closed etc the script continues to run in the background unless the process or server are shut down? Thanks

I am not sure how "best practice" this is but you could do: Add the program to: /etc/rc.d/rc.local This will have the program run at startup. If you add an '&' to the end of the line it will be run in the background. If you dont want to run the program manually (not at startup) you could switch to another tty by pressing ctrl + alt + f1, (this opens tty1 and will work with f1 - f6) then run the command. This terminal you do not have to have open in a window so you dont have to worry about it getting closed. To return to the desktop use ctrl + alt + f7.

When I run my tests I get a syntax error: SyntaxError: (unicode error) 'utf-8' codec can't decode byte 0xa7 in position 0: invalid start byte The cause of this seems to be that I use a § in a string on line 62. I'm using python 3.4.2 for the project and have used § elsewhere without getting a error. I got a friend to open the project as well, on his screen the § in tests.py showed up as question marks, but this was only in the test files, in the other places it had been used it showed up as normal. I got him to change the § that were showing up as question marks to § on his pc and it worked, which is really weird. How would I go about fixing something like this on my computer though? I can't really get him to load up the file and insert special character every time I want to use them in tests. edit: So I found out pycharm for some reason had set only tests.py to a encoding other than utf-8. I changed this to utf-8 and it then showed the § I had written as question marks. However swapping them out for § did not work for me. The reason is that for some reason even though the encoding is set to utf-8, pycharm still displays latin1 for me and type latin1 characters instead of utf-8. I've tested on 2 other computers (1 mac, and 1 windows 8.1 same as the one I have problems with) where it correctly displays utf-8. On those computers my § still appear as question marks, but if i change it on the other computer it now appears as Â§ on the computer with the problem. So my problem now is to get pycharm to properly use UTF-8 instead of latin 1.

Ok so I found the problem. as patrys sugested in a comment the file didn't use UTF-8 as encoding. To change that in pycharm I had to go to file->settings->editor->file encodings and change the file encoding for tests to utf-8. After I did that I had to go into the file and re eddit the § as they have now turned into question marks. However it still didn't work. I found out that I also have to change it to UTF-8 down in the right corner of pycharm. For some reason tests is the only .py file that was affected by this (even though I deleted the original tests.py file and remade it).

The main advantage of Nginx is cited as it not needing to spawn separate threads for each request it receives. Now, if we were to run a python based web application using FastCGI, and this web application has blocking calls, would this create a bottleneck? Since there is only a limited number of workers running(1 per processor?), wont a blocking call by a python script make it cooperative multiprocessing?

Nginx talks to a fastcgi process over a socket connection. If the fastcgi process blocks, that means that it won't be sending data over the socket. This won't block nginx as such, because it keeps processing events (data from other connections). It uses non-blocking techniques like select, poll or equivalent OS-dependent functions (with a timeout) to query sockets without blocking. But it will stall whatever client is waiting for the fastcgi output.

I need to change text documents. The way I've been doing it is making a new file, copying everything line by line from the old file and making changes on the way, then saving the new file as the old file's name. This becomes a problem when I only have read permission on the file. First I get OSErrno 30, not letting me delete the old file at the end of the writing. If I change my open command to 'r+', it simply says the file is not found. I don't have root access. Does anyone know of a workaround to this problem? EDIT: Thanks for the responses. I guess that IS the intended behavior of a read-only file...

So that it would Entropy efficient and take less time to compress and decompress the ECG signal. I am totally stuck how I go through to achieve this. I am open to any programming language.

Reconsider your choice of the LZ 77/78 algorithms. ECG waves look similar but they are not binary identical so the dictionary-based compression algorithms don't provide ideal results. Complicated algorithms can hardly be expressed in few lines of code.

You would need a compiler that will translate whatever language you're writing in (in the case of Java, an implementation of the JVM as well) to the assembly used by the calculator's CPU, it's probably not likely you will find an easy to use solution as calculators like the TI-84 are pretty archaic.

After a little research, I found some some hand-held "pocket" devices. The Palm m500 has a JVM to program java on. There apparently was a website that had an SDK for C, but the website was removed. In regards to calculators: TI-82, 83, 84, 85, 86, and related models all support TI-BASIC and z80 ASM. TI-92, Voyage 200, TI-89, and related models all support TI-BASIC, C, and 68000 ASM.

Python has a special script that is run on startup. On my platform it is located at /usr/lib/python2.5/site-packages/sitecustomize.py IIRC. You may want to check that file for any script calls to that directory. Also, if you are on a linux machine you could check /etc/bashrc or /etc/profile.d. If that doesn't help, try to update your question with more specific information.

Help, I screwed up. I have a somewhat complex python script that is currently running in a putty window to a Ubuntu server. I accidentally overwrote the script using another putty window, so the copy on the hard drive is now gone, but the script is still running from memory in the first window. This happened before I had a chance to run my backups for this folder. Is there a way I can get the script, (that is currently running) from the memory in the first putty window? I haven't stopped the script, my guess is once I stop it it will be gone forever. Can I send it to a background process somehow (some hot key,) then glean the script from a memory dump or something. I assume something like this would have to happen from the actual window from which the script is running. It would be nice if I could get the .py back, I heard Python compiles the script before running, if that is the case, the human readable part may be gone. Sigh, it has been a stressful day. Thanks for any help, Mark.using

As far as I know, Python doesn't keep the source in memory, and the method presented in the comment only keeps executables alive, not scripts. Dumping the memory of the program probably allows you to get to the bytecode, but I have no idea how much effort that might require. Instead, I'd first try a non-Python-specific approach that I've succesfully used to recover Python sources that I've accidentally deleted. This assumes the filesystem is ext2/3/4 and that you have root access. The first step (in any recovery) is obviously to try to avoid writing any files on the system so as to not overwrite the data that you are looking for. On a home system I'd probably personally remount the partition as read-only if possible to avoid any more writes going through. I've heard other people recommend just quickly pulling the plug, which might prevent the OS/disk cache from being written to the disk and perhaps save you some additional data (or even prevent the deletion) if you're really quick about it. On a remote system, neither of these is probably a good idea (unless the data is really important and you can get the disk shipped to you or something) since the system might not like it if something goes read-only all of a sudden. The second step is to execute debugfs /dev/sdXY, where /dev/sdXY is the partition that the deleted file was on. In the prompt, say blocks /path/to/the/directory/the/removed/file/was/in. Then, give the blocks command paths to other existing files in the directory. Now, exit the program by saying quit, and hope that the block numbers you saw were close to each other. If the directory is old and the block numbers scattered, start with a recent file's block numbers. (That is, one that has been last modified as close in time to the removed file's last modification time as possible) We will try to scan the contents of the partition near the other files in the directory under the assumption that the files was stored close to them. Execute dd if=/dev/sdXY bs=4096 skip=BLOCKNUMBER count=COUNT |grep -C APPROXIMATE_LINE_COUNT_OF_THE_REMOVED_FILE WORD, where BLOCKNUMBER is a number somewhere before the first block number, COUNT is some suitable number of blocks to search and WORD is a word that was contained in the source file. If you don't get anything, try fishing near another file's blocks. If time is not an issue, and you can think of a string that only occurred in the removed file (so you don't get too many false positives), you might just skip all that and scan the whole disk with grep -a WORD -C LINECOUNT /dev/sdXY. Another method (that you should try before the other one) that probably won't work for you since IIRC recent versions of Ubuntu (and probably other systems too) by default configure the kernel to block access to /dev/mem, is trying to scan the memory for the file. Just do grep -a WORD -C LINECOUNT /dev/mem to scan memory instead of the partition. (This can also save your day if you've written a long text in a form field and you misclick and your browser empties the field)

I have used python to write script for Photoshop using versions from CS6 to CC 2014 and my scripts have worked flawlessly. Last week I updated my Photoshop to CC 2015 and my scripts stopped working. I got error messages about missing attributes. I thought this was due to CC 2015 having changed something about the COM interface. When I checked the available attributes, I noticed that only a small subset of all the attributes was avilabe. I then reinstalled the CC 2014 but the problem did not disappear, I still see just a small subset of the attributes, all the rest gave the same error message. I noticed the splash screen had changed from my previous version of CC 2014 which may mean that some changes has been made in my newer CC 2014 as well. I can still run the script on my old machine with CS6. I have of course run makepy prior to using the new Ps version. I have tried two approaches: win32com and comtypes. Neither works. I get different sets of exported methods for the win32com and comtypes approaches which is surprising. I am very dependent on my scripts and would like to find a solution. If you are using Photoshop CC 2014 with python, I recommend you don't upgrade until this problem is solved.

It seems this is due to a change in the Photoshop API. You may want to report it to them and get the right feedback. Since most of the stackflow user might be more "code-oriented", it is likely that you won't get effective answer.

I have a bash script to automate few things I do. The bash calls 2 python scripts, If I run the bash script normally, everything runs, no errors what so ever. I set up a cron job to Automate this and when I checked the logs I noticed the python scripts don't run at all. It gives me the following error. python: can't open file 'movefiles.py': [Errno 2] No such file or directory python: can't open file 'create_log_shimmer.py': [Errno 2] No such file or directory Both these files exist and runs when calling the bash script directly.

The working directory of the cron is different from the directory you run the script directly. Make your bash script to use absolute path for python script files. Or make the bash script to change directory to where you run the script directly.

There is no specific GETfeature that would allow that. What you'll need to do is create a search for that keyword and Get search/tweets and use the since_id and max_id like you have and look at time_created_at from the JSON and filter yet again using that. The problem with the previous step is that you're limited to 180 tweets /15 minutes. Another solution is to use the streaming API since it'll give you recent information most are within 5 minutes and you'll be able to filter by keywords as well.

I prepare some test suites for an e-commerce web site, so i use Selenium2Library which requires a running browser on a display. I am able to run these test on my local machine but i had to run them on remote server which does not have an actual display. I tried to use xvfb to create a virtual display but it did not worked, tried all solutions on some answers here but nothing changed. So i saw pyvirtualdisplay library of Python but it seems like helpful with tests written in Python. I'd like to know that if I am able to run test suites that i wrote in robotframework (which are .txt formatted and could be runnned via pybot) via Python so i can use pyvirtualdisplay? Sorry about my English, thanks for your answers...

In Eclipse, I have the following Console output Logfile: File "C:\temp2\file1.log", line 1 Testimplementierung: File "A:\TestSafety\file2.py", line 222 Both paths are shown as hyperlinks. When I click these hyperlinks in Eclipse Kepler, the files are openend in the Python Text Editor (this is what I want). When I click these hyperlinks in Eclipse Luna or Mars, it works for the second file. For the first file, I get a dialog "The definition was found at: C:\temp2\file1.log (which cannot be opened because it is a compiled extension)" Whats going wrong here? Note: A:\TestSafety is my Eclipse Project. C:\temp2 is outside of my Eclipse workspace. Somebody told me I should add a "Link to existing source" into my Eclipse project, which seemed to work for a file, now it is broken again and I don't know why.

It seems I've found the solution: Open Window -> Preferences, goto PyDev -> Editor -> Code Style -> File Types, look for "Valid source files (comma-separated)" and append ", log". The file extensions listed in this filed are evaluated by FileTypesPreferencesPage.java:getDottedValidSourceFiles(), which is called by PythonPathHelper.java:isValidSourceFile(), which is called by PyGoToDefinition.java:doOpen(), which is the method raising the error message. Now my *.log file opens when I click on a hyperlink to it in the Text-Editor.

When you publish the unit test results in the post build section (If you aren't already, you should), you set the thresholds for failure. If you don't set thresholds, the build will always fail unless running them returns a non zero exit code. To always fail the build on any unit test failure, set all failure thresholds to zero. Note that you can also set thresholds for skipped tests as well.

However run as a crontab, the server returns me this error: Traceback (most recent call last): File "/home/ws/undwv/mindfactory.py", line 7, in from bs4 import BeautifulSoup ImportError: No module named bs4 Since I do not have any root access to the server, BeautifulSoup was installed at the user directory: $HOME/local/lib/python2.7/site-packages I suppose the cron tab does not look for modules in the user directory.

I started HiveMQ with command as ./bin/run.sh . A window opens and confirm that HiveMQ is running..Great !!!. I started this with putty and when I close the putty , HiveMQ also stops. How to make HiveMQ run all the time ?. I am using the HiveMQ for my IoT projects ( raspberry pi). I know to subscribe and publish to HiveMQ broker from python , but what confuses me is , should I be running the python program continuously to make this work ?. Assuming I need to trigger 2+ GPIO on Pi , can I write one program and keep it running by making it subscribe to 2+ topic for trigger events ?. Any help is greatly appreciated. Thanks

We use Python Nose for unit testing our GUI app components and application logic. Nose runs all tests in one process, not a big problem for the application logic but for a complex C++/Python lib like PyQt, this is a problem since there is "application wide" state that Qt creates, and it is hard to ensure that cleanup occurs at the right time such that every test method has a "clean Qt slate". So I would prefer to have Nose start a separate Python process for each test method/function (or at least those that are flagged as needed this). I realize this would slow down the test suite but the benefit should outweigh the cost. I have seen the Insulate and the Multiprocess plugins but neither do this (Insulate only starts separate proc if a crash occurs -- Multiprocess just tries to use N process for N cores). Any suggestions?

I'm using jira-python to automate a bunch of tasks in Jira. One thing that I find weird is that jira-python takes a long time to run. It seems like it's loading or something before sending the requests. I'm new to python, so I'm a little confused as to what's actually going on. Before finding jira-python, I was sending requests to the Jira REST API using the requests library, and it was blazing fast (and still is, if I compare the two). Whenever I run the scripts that use jira-python, there's a good 15 second delay while 'loading' the library, and sometimes also a good 10-15 second delay sending each request. Is there something I'm missing with python that could be causing this issue? Anyway to keep a python script running as a service so it doesn't need to 'load' the library each time it's ran?

I'm writing some threaded python code in vim. When I run my tests, with :! py.test test_me.py Sometimes they hang and cannot be killed with ctrl-C. So I have to background vim (actually the shell the tests are running in) and pkill py.test. Is there a better way to kill the hanging test suite? I tried mapping :map ,k:! pkill py.test but this doesn't work since while the tests are running my input is going to the shell running the test, not vim. EDIT: I'm looking for a way to kill the test process that is quicker than ctrl-Z, pkill py.test, fg <cr> to return to editing. Ideally just a hotkey.

When you do :! in Vim, you effectively put Vim into background and the running process, in this case py.test, gets the focus. That means you can't tell Vim to kill the process for you since Vim is not getting keystrokes from you. Ctrl-Z puts Vim into background while running py.test because Vim is the parent process of py.test. Thus the shell goes through the chain then puts all children as well as the parent into background. I would suggest that you open another terminal window and do all the housekeeping chores there.

I have set up an Import.io bulk extract that works great with say, 50 URLs. It literally zips through all of them in seconds. However, when I try to do an extract of 40,000 URLs, the extractor starts very fast for the first thousand or so, and then progressively keeps getting slower every incremental URL. By 5,000 it literally is taking about 4-5 seconds per URL. One solution that seems to work is breaking them into chunks of 1,000 URLs at a time and doing a separate bulk extract for each. However, this is very time consuming, and requires splicing back together all of the data at the end. Has anyone experienced this, and if so do they have a more elegant solution? Thanks, Mike

One slightly less elegant solution would be to create a crawler. And before you run it insert the the 10k URLs in the "where to start crawling" box. Under advanced options set the crawl depth to zero, that way you will only get the pages you put in the where to start crawling input box. That should do the trick. Plus the cawler has a bunch of other options like wait between pages and concurrent pages etc.

Import.io bulk extract slows down when more URLs are in list

I have set up an Import.io bulk extract that works great with say, 50 URLs. It literally zips through all of them in seconds. However, when I try to do an extract of 40,000 URLs, the extractor starts very fast for the first thousand or so, and then progressively keeps getting slower every incremental URL. By 5,000 it literally is taking about 4-5 seconds per URL. One solution that seems to work is breaking them into chunks of 1,000 URLs at a time and doing a separate bulk extract for each. However, this is very time consuming, and requires splicing back together all of the data at the end. Has anyone experienced this, and if so do they have a more elegant solution? Thanks, Mike

Mike, would you mind trying again? We have worked on the Bulk Extract, now it should be slightly slower at the beginning, but more constant Possibly 40k are still too many, in which case you may try to split, but I did run 5k+ in a single run Let me know how it goes!

is there any way to constantly "listen" to a website and run some code when it updates? i'm working on earthquake data, specifically, parsing earthquake data from a site that updates and lists earthquake details in real time. so far, my only (and clunky) solution has been to use task scheduler to run every 30 minutes, which of course would have a time difference of 1-29 minutes depending on when the event will happen between the 30 minute downtime between running the code. i also thought of using some twitter API, since the site also has an automated twitter account tweeting details every time an earthquake happens, but again this would require constantly "listening" to the twitter stream via python as well. would appreciate help, thanks.

is there any way to constantly "listen" to a website and run some code when it updates? If the site offers a feed or stream of updates, use it. However, if you are looking to scrape a page and trigger code on differences, then you need to poll the site like you are doing (clumsily) with TaskScheduler.

Hi there I'm trying to deploy my python app using Travis CI but I'm running into problems when I run the "travis setup heroku" command in the cmd prompt. I'm in my project's root directory, there is an existing ".travis.yml" file in that root directory. I've also installed ruby correctly and travis correcty because when I run: "ruby -v" I get "ruby 2.2.2p95 (2015-04-13 revision 50295) [x64-mingw32]" "travis -v" I get "1.7.7" When I run "travis setup heroku" I get this message "The system cannot find the path specified" then prompts me for a "Heroku API token:" What's the issue?

If you hadn't had Heroku Toolbelt setup to the $PATH environment variable during installation, here are some steps to check: Check if Heroku toolbelt is set in PATH variable. If not, cd to your Heroku toolbelt installation folder, then click on the address bar and copy it. Go to the Control Panel, then click System and Advanced System Protection. Go to Environment Variables, then look for $PATH in the System Variables After the last program in the variable, put a ; then paste in your Heroku CLI folder and click OK. (This requires cmd to be restarted manually) Login to Heroku CLI grab the token key from heroku auth:token run travis setup heroku if the setup goes smoothly, you shouldn't get the command not found and prompt you for heroku auth key. It will ask that you want to encrypt the auth key (highly recommend) and verify the information you provided with the toolbelt and Travis CLI. commit changes you should be able to get your app up and running within your tests.

If you're talking about notifications you can disable them per-account or entirely on a project via the integration. That said if all the messages are the same you should look into why they're not grouping. A common case would be you're using a logging integration and there's a variable in the log message itself.

I'd like to have advertisements in an android App I've written and built using PGS4A. I've done my research and all, but there doesn't seem to be any online resources that explains how to do that just yet. I haven't much knowledge on Java either, which is clearly why I've written that in Python. Has anyone found a way to achieve that? If not, how difficult would it be to convert the project files into an Android Studio (or even an Eclipse) project? (so then one can just implement the ads following the Java Admob documentation found everywhere) Thank you in advance.

To access Java already implemented version you can use pyjnius. I tried to use it for something else and I didn't succeed. Well, I yielded pretty quickly because it wasn't necessary for my project. Otherwise, I am afraid, you will have to implement it yourself from scratch. I never heard about a finished solution for your problem. If you succeeded to use PGU, it wouldn't be so hard. If not, well, I wish you luck, and put your solution online for others. There is an Eclipse plug-in for Python. I think that Android studio does not support PGS4A. Never needed it. Console is the queen.

I have written a python script that is designed to run forever. I load the script into a folder that I made on my remote server which is running debian wheezy 7.0. The code runs , but it will only run for 3 to 4 hours then it just stops, I do not have any log information on it stopping.I come back and check the running process and its not there. Is this a problem in where I am running the python file from? The script simply has a while loop and writes to an external csv file. The file runs from /var/pythonscript. The folder is a custom folder that I made. There is not error that I receive and the only way I know how long the code runs is by the time stamp on the csv file. I run the .py file by ssh to the server and sudo python scriptname.I also would like to know the best place in the linux debian directory to run python files from and limitations concerning that. Any help would be much appreciated.

Basically you're stuffed. Your problem is: You have a script, which produces no error messages, no logging, and no other diagnostic information other than a single timestamp, on an output file. Something has gone wrong. In this case, you have no means of finding out what the issue was. I suggest any of the following: either adding logging or diagnostic information to the script. Contacting the developer of the script and getting them to find a way of determining the issue. Delete the evidently worthless script if you can't do either option 1, or 2, above, and consider an alternative way of doing your task. Now, if the script does have logging, or other diagnostic data, but you delete or throw them away, then that's your problem and you need to stop discarding this useful information. EDIT (following comment). At a basic level, you should print to either stdout, or to stderr, that alone will give you a huge amount of information. Just things like, "Discovered 314 records, we need to save 240 records", "Opened file name X.csv, Open file succeeded (or failed, as the case may be)", "Error: whatever", "Saved 2315 records to CSV". You should be able to determine if those numbers make sense. (There were 314 records, but it determined 240 of them should be saved, yet it saved 2315? What went wrong!? Time for more logging or investigation!) Ideally, though, you should take a look at the logging module in python as that will let you log stack traces effectively, show line numbers, the function you're logging in, and the like. Using the logging module allows you to specify logging levels (eg, DEBUG, INFO, WARN, ERROR), and to filter them or redirect them to file or the console, as you may choose, without changing the logging statements themselves. When you have a problem (crash, or whatever), you'll be able to identify roughly where the error occured, giving you information to either increase the logging in that area, or to be able to reason what must have happened (though you should probably then add enough logging so that the logging will tell you what happened clearly and unambiguously).

I am new to python. I read unittest docs. In the documentation about tearDown() method, I found following lines "This is called even if the test method raised an exception, so the implementation in subclasses may need to be particularly careful about checking internal state." What does this statement conveys ? Can you let me understand me with the help of some good example, where the internal statement can create havoc ? Thanks in advance. EDIT : I got some answers, but they are quite simple. I need some examples, where some state is involved, like tests involving database and so on.

From the OP: "This is called even if the test method raised an exception, so the implementation in subclasses may need to be particularly careful about checking internal state." The first things this conveys is that you can be sure that teardown is called whatever happens in your test methods. Consequently this means that you should not have any teardown code in your test method, you should move it into the teardown method. However, if you do have an exception in your test method, this may mean that the state of your test instance may be different on different test runs and the teardown method must take this into account, or you must structure your code so that it will always work. An example may be that you test code involves the creation of tables in the database. If you have an exception, then maybe not all the tables are created, so teardown should make sure it doesn't try to drop non-existent tables. However, the better way might be for setup to start a transaction and teardown to rollback the transaction.

I have this python setup using objects that can perform specific tasks for I2C protocol. Rather than having the script create objects and run a single task when run from a command line command, is there a way to have the objects 'stay alive' in the background and somehow feed the program new data from the command line? The general idea is to have something running on a remote pc and use ssh to send commands (new data) over to the program. One idea I had was to have the program constantly check (infinite loop) for a data file containing a set of tasks to perform and run those when it exists. But it seems like it could go awry if I were to sftp a new data file over because the program could be reading the one that already exists and cause undesirable effects. I'm sure there are many better ways to go about a task like this, any help will be appreciated.

You can try and use a client-server or sockets approach. Your remote PC has a server running listening to commands or data coming into. Your client or local computer can send commands on the port and ip that the remote PC is listening to. The server then parses the data coming in, looks at whatever commands you have defined and executes them accordingly.

I want to debug a c++ program using gdb. I use the pi and the py commands to evaluate python commands from within gdb, which works fine when I invoke gdb from the command line. However, when I invoke gdb from within emacs using M-x gdb and then gdb -i=mi file_name, the following errors occur: the pi command correctly opens an interactive python shell, but any input to this shell yields the errors like this: File "stdin", line 1 -interpreter-exec console "2" SyntaxError: invalid syntax the py command works correctly for a single command (like py print 2+2), but not for multiple commands I can get around those problems by starting gdb with gud-gdb, but then I dont have the support for gdb-many-windows. Maybe the problem is caused by the prompt after typing pi, which is no longer (gdb) but >>> instead?

I am going to go out on a limb and say this is a bug in gud mode. The clue is the -interpreter-exec line in the error. What happens here is that gud runs gdb in a special "MI" ("Machine Interface") mode. In this mode, commands and their responses are designed to be machine-, rather than human-, readable. To let GUIs provide a console interface to users, MI provides the -interpreter-exec command, which evaluates a command using some other gdb "interpreter" (which doesn't mean what you may think and in particular has nothing to do with Python). So, gud sends user input to gdb, I believe, with -interpreter-exec console .... But, in the case of a continuation line for a python command, this is the wrong thing to do. I tried this out in Emacs and I was able to make it work for the python command when I spelled it out -- but py, pi, and python-interactive all failed.

Pretty new to all this so I apologize if I butcher my explanation. I am using python scripts on a server at work to pull data from our Oracle database.

If I log back in again I have to re-set the path. Anything I can do to make this permanent? I'm trying to use Cron as well to automate the script once a week.

I'm looking to backup a subreddit to disk. So far, it doesn't seem to be easily possible with the way that the Reddit API works. My best bet at getting a single JSON tree with all comments (and nested comments) would seem to be storing them inside of a database and doing a pretty ridiculous recursive query to generate the JSON. Is there a Reddit API method which will give me a tree containing all comments on a given post in the expected order?

The number of comments you get from the API has a hard limit, for performance reasons; to ensure you're getting all comments, you have to parse through the child nodes and make additional calls as necessary. Be aware that the subreddit listing will only include the latest 1000 posts, so if your target subreddit has more than that, you probably won't be able to obtain a full backup anyways.

On a well tested project, coverage would be ideal but with some untested legacy code I don't think there is a magical tool. You could write a big test loading all the pages and run coverage to get some indication. Cowboy style: If it's not some critical code and you're fairly sure it's unused (i.e. not handling payments, etc.). Comment it out, check that the tests pass, deploy and wait a week or so before removing it definitely (or putting it back if you got a notification).

I'll just add that to use Python with Apache you'll have to enable mod_wsgi or mod_python or just write a standard CGI or FastCGI script. I think bottle/flask supports all methods. There is somewhere compiled JVM with support for hardware floating points, and that version should work a little better. But, well, Raspberry Pi and Java aren't exactly friends. I admit, it is a little odd, because we know that Java works perfectly fine on ARMs (e.g. Android), but current state for RasPi is as it is.

The best way to give non-technical users access to DataNitro is to copy the VBA interface: hook the script up to an Excel button and have users press that button to run it. (There's no difference between running a Python script with DataNitro and running VBA code from the user's point of view.) Each person using the script would need a DataNitro license. There's no way to make DataNitro work with py2exe, unfortunately. Source: I'm one of the DataNitro developers.

So I have a set of points in a city (say houses or residences) and I want to find the shortest distance between these points and a set of candidate points for a store. I am looking for the best store locations that will minimize the distance to all of the houses in the set. So I will iteratively move the candidate store points and then recompute the distances between each store and house (again using Djikstra's algorithm). Because of the sheer volume of calculations, I cannot keep hitting the database for each iteration of the optimization algorithm. I have used pgrouting many times and this would work, however it would be too slow because of the large number of points and the fact that it has to search the disk each time. Is there a tool where I an load some small Open Street Maps city map in memory and then calculate the shortest routes in memory? I would need something fast, so preferably in C or python? But any language is okay as long as it works.

Heres and idea. Get the latlongs of the house and all the stores. Calculate the geohash of all points(house and stores) with maximum precision (12) and check if geohash of any stores matches that of the house. If it doesnt, calculate the geohash with lower precision (11) and then rinse and repeat till you get a store(May be multiple Ill get into that later) that matches the geohash of the house. This is a fuzzy-distance calculation. This will work great and with minimal processing time. But this will fail if you get two or more stores with the same geohash with some precision. So this is what I recommend you do The geohash loop with decreasing precision. Break when geohash of store(s) match the gohash of the house IF (more than one sores match) Go for plain distance calculation and find the closest store and return it ELSE return the one store that the matches the geohash Advantage of this method : Changes your strict requirements to a fuzzy probability problem. If you get a single sore, great. If you dont at least you reduce the number of candidates for distance calculation Disadvantage of this method: What if all stores land in the same geohash ? We introduce the same complexity here. Youll be banking on the chances that not all(or most) stores come under the same geohash. Realistically speaking, the disadvantage is only a disadvantage in corner cases. So overall you should soo performance improvement

I am working for a company who wants me to test and cover every piece of code I have. My code works properly from browser. There is no error no fault. Except my code works properly on browser and my system is responding properly do I need to do testing? Is it compulsory to do testing?

Whether it’s compulsory depends on organization you work for. If others say it is, then it is. Just check how tests are normally written in the company and follow existing examples. (There’re a lot of ways Django-based website can be tested, different companies do it differently.) Why write tests? Regression testing. You checked that your code is working, does it still work now? You or someone else may change something and break your code at some point. Running test suite makes sure that what was written yesterday still works today; that the bug fixed last week wasn’t accidentally re-introduced; that things don’t regress. Elegant code structuring. Writing tests for your code forces you to write code in certain way. For example, if you must test a long 140-line function definition, you’ll realize it’s much easier to split it into smaller units and test them separately. Often when a program is easy to test it’s an indicator that it was written well. Understanding. Writing tests helps you understand what are the requirements for your code. Properly written tests will also help new developers understand what the code does and why. (Sometimes documentation doesn’t cover everything.) Automated tests can test your code under many different conditions quickly, sometimes it’s not humanly possible to test everything by hand each time new feature is added. If there’s the culture of writing tests in the organization, it’s important that everyone follows it without exceptions. Otherwise people would start slacking and skipping tests, which would cause regressions and errors later on.

I'm developing a python script that runs as a daemon in a linux environment. If and when I need to issue a shutdown/restart operation to the device, I want to do some cleanup and log data to a file to persist it through the shutdown. I've looked around regarding Linux shutdown and I can't find anything detailing which, if any, signal, is sent to applications at the time of shutdown/restart. I assumed sigterm but my tests (which are not very good tests) seem to disagree with this.

When Linux is shutting down, (and this is slightly dependent on what kind of init scripts you are using) it first sends SIGTERM to all processes to shut them down, and then I believe will try SIGKILL to force them to close if they're not responding to SIGTERM. Please note, however, that your script may not receive the SIGTERM - init may send this signal to the shell it's running in instead and it could kill python without actually passing the signal on to your script. Hope this helps!

I have a python file which starts 2 threads - 1 is daemon process 2 is to do other stuff. Now what I want is to check if my 2 thread is stopped then 1 one also should stop. I was suggested to do so by cron job/runnit.. I am completely new to these so can you please help me achieve the goal Thanks

The best way out is to create this daemon as a child thread so it automatically gets killed when parent process is killed
