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 protected]
Chapter 2 - Pygame Basics 
Unfortunately, the links in the book aren't working yet, but should be in a few days.
thanks for your hard work, I am reading this chapter, Page 7, Colors section:"this means Pygame can draw 16,581,375 different colors (that is, 255 x 255 x 255 colors).", I think it might be "this means Pygame can draw 16,777,216 different colors (that is, 256 x 256 x 256 colors)."
