The following project page contains the Python Snippets useful for various tasks:
http://uthcode.googlecode.com/svn/trunk/python/
You may checkout the programs using the command
svn checkout http://uthcode.googlecode.com/svn/trunk/python/ python-snippets
Source code is most-often commented. My plan with uthcode is, it should eventually have a literal inclusion of programs and explaination of the code.
