Here's the introductory chapter to my next book on Python and Pygame. It assumes you have some Python and programming experience (if you don't, give a look to Invent with Python), and offers a quick view of all of the major parts of Pygame.
The chapter by itself is a good introduction to Pygame. If you've been meaning to give Pygame a look, then download the chapter. Please email in any questions or suggestions you have: email@example.com
Unfortunately, the links in the book aren't working yet, but should be in a few days.
