When I began this project, I thought it would be easy to get libraries for common stuff like matrix math, so I chose to work in Python 3.1- it being the most recent, updated version of the language. Unfortunately, NumPy is only compatible with 2.5 and 2.6 and seems to be the only game in town! Even other stuff that I turned up like gam...

Hi, I am pretty good with Python, so pseudo-code will suffice when details are trivial. Please get me started on the task - how do go about crawling the net for the snail mail addresses of churches in my state. Once I have a one liner such as "123 Old West Road #3 Old Lyme City MD 01234", I can probably parse it into City, State, Street,...
No flaming please, asking as a community wiki so nobody gets reputation here. I know python is not the first language to have list comprehension. I'm just interest in the history of the name. I'm particularly interested in why it's called comprehension ...

Are there any exemplary examples of the GoF Observer implemented in Python? I have a bit code which currently has bits of debugging code laced through the key class (currently generating messages to stderr if a magic env is set).

I have an application wich is minimized to the tray (showing an icon) when the user close it. What I need to know is how can I call it back with a combination of keys, like Ctrl+Alt+Something. Actually I call it back when I double-click it, but it will be nice to do the same on a keystroke. Here is a portion of the code: # -*- coding: u...
