Importing package with zip-archives
I'd like to have the following structure of my Python code: I have a directory called 'mysystem'. In this directory, I have files 'comp1.zip' and 'comp2.zip' etc which are zipped archives with python packages and modules.

Okay, so! I actually never quite got around to learning to do deep and useful magic with decorators. I've only ever done the most basic things with them. Its all been a little fuzzy in my head: things like what order decorators end up being called in if there's more then one, etc. But in my current situatio... 3 Jul 2010 02:37

delegation pattern via descriptor
hello, friendliest prog lang community on earth ;) i'm feeling that (0) delegation pattern thru descriptor encourages dedicated delegate for each task, if feeling: print(benefits) (1) the delegate is designed to be blind about the class on which the delegate is attached to isn't that the two strengthen the co... 9 Jul 2010 22:43

GAE + recursion limit
Hi, I'm writing a small translator using pyparsing library v1.5.2 (http://pyparsing.wikispaces.com/) and I'm using it both from command line and on Google App Engine. Recently I checked one of my samples which runs perfect from CLI against GAE and it throws me "RuntimeError 'maximum recursion depth exceeded'". ... 5 Jul 2010 05:37
