http://www.python.org/doc/faq/programming.html#how-do-you-set-a-global-variable-in-a-function

This and many other questions are answered in the Frequently
Asked Questions (FAQ) list.

Also make sure you've read the tutorial 
http://docs.python.org/tut/tut.html as it (I expect) would
answer that question as well.
