Ask HN: Simple exercises for a python beginner?

I've been helping a complete beginner to learn the basics of python. He's got a basic understanding of loops, conditionals, and input and print statements, plus a few functions, and knows how to use a text editor to write code. He really wants some simple programming exercises he can do to help him consolidate his knowledge. I've given him a few exercises I made up, but we are looking for more. Is there a good resource for this ( not project Euler! ), or do people here have any ideas?
