Here's some guides that I've found useful, or, potentially useful when it comes to pygame:

This guide seems to be pretty good for getting started in pygame. I keep meaning to look through it more, but haven't had a chance to.

Invent with Python also covers game design as well as learning to program in Python. It's primarily aimed at kids (supposedly), however it covers a lot. It starts out with some text-based games, but then moves on to using pygame.

This tutorial isn't too bad, and mostly works. He's got exercises to go with the lessons, with IMO is quite helpful.

Hope someone finds them useful!
