Howdy, codeboys and codegirls! I have came across a simple problem with seemingly easy solution. But being a Python neophyte I feel that there is a better approach somewhere. Say you have a list of mixed strings. There are two basic types of strings in the sack - ones with "=" in them (a=potato) and ones without (Lady Jane). What you n...
If you had switched from php + (framework of choice) to python + (framework of choice) as your development platform, what would you say have been the upsides/gains of the switch?

I try to avoid "global" statements in python and http://stackoverflow.com/questions/146557/do-you-use-the-global-statement-in-python suggests this is a common view. Values go into a function through its arguments and come out through its return statement (or reading/writing files or exceptions or probably something else I'm forgetting)....

First of all, the problem is that program fails with double memory freeing ... The deal is: I have FooCPlusPlus *obj; and I pass it to my script. It works fine. Like this: PyObject *pArgs, *pValue; pArgs = Py_BuildValue("((O))", obj); pValue = PyObject_CallObject(pFunc, pArgs); where pFunc is a python function... So, my script ha...

I would like to write a small script that does the following (and that I can then run using my crontab): Look into a directory that contains directories whose names are in some date format, e.g. 30-10-09. Convert the directory name to the date it represents (of course, I could put this information as a string into a file in these direc...
Hello! How to add strings to the axes in Axes3D instead of numbers? I just started using the matplotlib. I have used Axes3dD to plot similar to the example given on their website (http://matplotlib.sourceforge.net/examples/mplot3d/bars3d%5Fdemo.html). Note that one must use the last verson (matplotlib 0.99.1), otherwise the axis gets a...

Is it possible to extract type of object or class name from message received on a udp socket in python using metaclasses/reflection ? The scenario is like this: Receive udp buffer on a socket. The UDP buffer is a serialized binary string(a message). But the type of message is not known at this time. So can't de-serialize into appropri...
Thanks to this answer I managed to come up with a temporary solution to my problem. However, with a list of 6000 points that grows everyday it's becoming slower and slower. I can't use a third party service* therefore I need to come up with my own solution. Here are my requirements: Clustering of the coordinates need to work with ...
Hi, besides from using a completely integrated IDE with debugger for python (like with Eclipse), is there any little tool for achieving this: when running a program, i want to be able to hook somewhere into it (similar to inserting a print statement) and call a window with an object inspector (a tree view) after closing the window, t...

Reading around for fscanf or sscanf says that the string is processed upto the first whitespace that is encountered. fgets doesn't help either as I still...
What are good python libraries for the following needs: MVC Domain Abstraction Database Abstraction Video library (just to create thumbnails) I already know that SQLAlchemy is really good for Database Abstraction so don't bother with it unless you want to suggest a better one.

I have a very simple model: class Artist(models.Model): name = models.CharField(max_length=64, unique=False) band = models.CharField(max_length=64, unique=False) instrument = models.CharField(max_length=64, unique=False) def __unicode__ (self): return self.name that I'm using as a model form: from django.forms import ModelForm...
Perl habits die hard. Variable declaration, scoping, global/local is different between the 2 languages. Is there a set of recommended python language idioms that will render the transition from perl coding to python coding less painful. Subtle variable misspelling can waste an extraordinary amount of time. I understand the variable de...
I have seen conflicting advice on whether the following code is better def function(): ret_val = 0 if some_condition(): ret_val = 2 else: ret_val = 3 return ret_val or whether this is better: def function(): if some_condition(): return 2 else: return 3 This is a simple example...
I extended django.utils.feedgenerator.Atom1Feed for my own needs and am trying to write some tests for it. It works fine from runserver and mod_wsgi. Basically, when feeds are accessed from the testrunner I'm running into these problems: 1) The item_title() and item_description() methods are never called, but item_pubdate(), item_link(...
