In preparation for the launch of the Raspi, I've been looking around on the intertubes for useful python tutorials (I'm a n00b). Here are a few I think are worth sharing (I'm focusing on game programming, but everything is welcome)
A very well written set of tutorials using Pygame, in an object-oriented-programming style
An introduction to PyQt4 - currently the only way to get openGL acceleration using Python on the Raspi (I think)
A Programmer’s Introduction to Python (free online e-book)
“Invent Your Own Computer Games with Python” (free e-book)
How to Think Like a Computer Scientist: Learning with Python (PDF)
