For the moment I recommend looking at The Python Tutorial by Guido van Rossum for more topics. If you have been following this tutorial, you should be able to understand a fair amount of it. If you want to get deeper into Python, Dive Into Python is a nice on-line textbook, although targeted at people with a more solid programming background. The Python Programming wikibook can be worth looking at, too.
This tutorial is very much a work in progress. Thanks to everyone who has sent me emails about it. I enjoyed reading them, even when I have not always been the best replier.
Happy programming, may it change your life and the world.
