I'm internationalizing a Python application, with two goals in mind: The application loads classes from multiple packages, each with its own i18n domain. So modules in package A are using domain A, modules in package B are using domain B, etc. The locale can be changed while the application is running. Python's gettext module makes ...

I'm learning Python as my second programming language (my first real one if you don't count HTML/CSS/Javascript). I'm trying to build something useful as my first real application - an IRC bot that alerts people via SMS when certain things happen in the channel. Per a request by someone, I'm (trying) to build in scheduling preferences ...
Google is sponsoring an Open Source project to increase the speed of Python by 5x. Unladen-Swallow seems to have a good project plan Why is concurrency such a hard problem? Is LLVM going to solve the concurrency problem? Are there solutions other than Multi-core for Hardware advancement? ...
I am using cProfile to profile the leading function of my entire app. It's working great except for some 3rd party libraries that are being profiled, and shown in the output as well. This is not always desirable when reading the output. My question is, how can i limit this? The documentation on python profilers mentions: p.sort_stats('...
I'm working on a script for work to extract data from an old template engine schema: [%price%] { $54.99 } [%/price%] [%model%] { WRT54G } [%/model%] [%brand%]{ LINKSYS } [%/brand%] everything within the [% %] is the key, and everything in the { } is the value. Using Python and regex, I was able to get this far: (?<=[%)(?P\w*?)(?=\%...
If a variable refers to either a function or a class method, how can I find out which one it is and get the class type in case it is a class method especially when the class is still being declared as in the given example. eg. def get_info(function_or_method) : print function_or_method class Foo(object): def _...
I am trying to get my Django app (NOT using Google app engine) retrieve data from Google Contacts using Google Contacts Data API. Going through authentication documentation as well as Data API Python client docs First step (AuthSubRequest) which is getting the single-use token works fine. The next step(AuthSubSessionToken), which is upg...
The pickle module seems to use string escape characters when pickling; this becomes inefficient e.g. on numpy arrays. Consider the following z = numpy.zeros(1000, numpy.uint8) len(z.dumps()) len(cPickle.dumps(z.dumps())) The lengths are 1133 characters and 4249 characters respectively. z.dumps() reveals something like "\x00\x00" (act...
I'm writing a module and want to have a unified exception hierarchy for the exceptions that it can raise. This allows users of the module to catch those particular exceptions and handle them distinctly, if needed. But many of the exceptions raised from the module are raised because of some other exception; e.g. failing at some task becau...
Is there a way to terminate a process started with the subprocess.Popen class with the "shell" argument set to "True"? In the working minimal example below (uses wxPython) you can open and terminate a Notepad process happily, however if you change the Popen "shell" argument to "True" then the Notepad process doesn't terminate. import w...
Lets say I have projects x and y in brother directories: projects/x and projects/y. There are some utility funcs common to both projects in myutils.py and some db stuff in mydbstuff.py, etc. Those are minor common goodies, so I don't want to create a single package for them. Questions arise about the whereabouts of such files, possibl...
I have a series of Python tuples representing coordinates: tuples = [(1,1), (0,1), (1,0), (0,0), (2,1)] I want to create the following list: l = [] for t in tuples: l[ t[0] ][ t[1] ] = something I get an IndexError: list index out of range.

What is the Python equivalent of following Perl code? hmac_md5_hex($login . "^" . $seq . "^" . $time . "^" . $amo . "^", $CryptoKey); The Python hashlib.md5 doesn't seem to take an "cryptographic key" argument. It only accepts 1 argument. ...

In Python 2.5, I import modules by changing environment variables. It works, but using site-packages does not. Is there another way to import modules in directories other than C:\Python25 ? ...
Given a class C in Python, how can I determine which file the class was defined in? I need something that can work from either the class C, or from an instance off C. The reason I am doing this, is because I am generally a fan off putting files that belong together in the same folder. I want to create a class that uses a Django template...
Has anyone ever tried that? ...
I need to process XML documents of varying formats into records in a MySQL database on a daily basis. The data I need from each XML document is interspersed with a good deal of data I don't need, and each document's node names are different. For example: source #1: <object id="1"> <title>URL 1</title> <url>http://www.one.com&...
