• Sorting a list of version strings

  - by Zack

  I have a list containing version strings, such as things: versions_list = ["1.1.2", "1.0.0", "1.3.3", "1.0.12", "1.0.2"] I would like to sort it, so the result would be something like this: versions_list = ["1.0.0", "1.0.2", "1.0.12", "1.1.2", "1.3.3"] The order of precendece for the digits should obviously be from left to right, and it should be decending. So 1.2.3 comes before 2.2.3 and 2.2.2 comes before 2.2.3. How do I do this in Python?

• Does a syntax for this exist? In any language?

  - by Michael

  It seems pretty common to me to have an argument, in a dynamically typed language that is either an Object or a key to lookup that object. For instance when I'm working with a database I might have a method getMyRelatedStuff(person) All I really need to lookup the related stuff is the id of the person so my method could look like this in python: def getMyRelatedStuff(person_or_id): id = person_or_id.id if isinstance(person,User) else person_or_id #do some lookup Or going the other direction: def someFileStuff(file_or_name): file = file_or_name if hasattr(file,'write') else open(file_or_name)

• Trying to provide a global logging function

  - by Gekitsuu

  I typically write my scripts with a structure like s #!/usr/bin/python import stuff def do_things(): print "FOO" def main(): do_things() if __name__ == "__main__": main() The problem I have is I'd like to have a logging function that is defined globally and I"m not really sure how to do this. I tried a decorator function but if I define it in main I can't call it from other functions in the script. It seems like something that should be easy to do but not something I have experience with.

• Auto-register class methods using decorator

  - by adamk

  I want to be able to create a python decorator that automatically "registers" class methods in a global repository (with some properties). Example code: class my_class(object): @register(prop1,prop2) def my_method( arg1,arg2 ): # method code here... @register(prop3,prop4) def my_other_method( arg1,arg2 ): # method code here... I want that when loading is done, somewhere there will be a dict containing: { "my_class.my_method" : ( prop1, prop2 ) "my_class.my_other_method" : ( prop3, prop4 ) } Is this possible?

• How to take advantage of subprocess within Django? - Django

  - by RadiantHex

  Hi folks, I'm currently using os.popen() but have been recommended to use subprocess.popen() instead. Any ideas on how I can integrate this? It would be cool and fun to have a Python shell accessible on a Django app. But I reckon that it might be a bit complex to implement. I guess I would have to retrieve the subprocess, as a new request comes in. Any ideas?

• What is the best book for learning about Algorithms?

  - by sheats

  I know what algorithms are, but I have never consciously used or created one for any of the programming that I have done. So I'd like to get a book about the subject - I'd prefer if it was in python but that's not a strict requirement. What book about algorithms helped you most to understand, use, and create algorithms? One book per answer so they can be voted on...

• Why are filename underscores better than hyphens

  - by Jasie

  From Building Skills in Python: "A file name like exercise_1.py is better than the name execise-1.py. We can run both programs equally well from the command line, but the name with the hyphen limits our ability to write larger and more sophisticated programs." Why?

• Get a list/tuple/dict of *all* the arguments passed to a function?

  - by Phillip Oldham

  Given the following function: def foo(a, b, c): pass How would one obtain a list/tuple/dict/etc of the arguments passed in? Specifically, I'm looking for Python's version of JavaScript's arguments keyword or PHP's func_get_args() method. What I'm not looking for is a solution using *args or **kwargs; I need to specify the argument names in the function definition (to ensure they're being passed in) but within the function I want to work with them in a list- or dict-style structure.

• How to apply a function to a collection of elements

  - by Cue

  Consider I have an array of elements out of which I want to create a new 'iterable' which on every next applies a custom 'transformation'. What's the proper way of doing it under python 2.x? For people familiar with Java, the equivalent is Iterables#transform from google's collections framework.

• What is the preferred syntax for initializing a dict?

  - by daotoad

  I'm putting in some effort to learn Python, and I am paying close attention to common coding standards. This may seem like a pointlessly nit-picky question, but I am trying to focus on best-practices as I learn, so I don't have to unlearn any 'bad' habits. I see two common methods for initializing a dict: a = { 'a': 'value', 'another': 'value', } b = dict( a='value', another='value', ) Which is considered to be "more pythonic"? Which do you use? Why?

• Which PHP calendar will suit my needs? Or build my own?

  - by John

  There are so many web based calendars out there that I'm not sure which will best suit my purposes. I want to create an events calendar, which I suppose looks and functions in much the same way as google calendar. But users shouldn't need to sign up for a gmail account or a google account. Users of my social network website should be able to create events in the calendar and share it with other friends in their "friend network". In month, year or day views, you can mouse hover events to see a bubble dialog that lists events in detail. People need to pay a monthly fee to use my website (not sure if this prevents me from using google apps). So is something like Google Calendar the way to go? Or are there other php/javascript calendars out there that already meet my needs? Or will it just save me more time to build my own?

• Has anyone used Sphinx to document a C++ project?

  - by Nick

  Sphinx is a new documentation tool for Python. It looks very nice. What I'm wondering is: How suitable this is for documenting a C++ project? Are there any tools for converting existing documentation (e.g. doxygen) to Sphinx format? Are there online/downloadable examples of C++ projects that use Sphinx? Any tips from anyone who has used Sphinx?
