I think Python Challenge is great.

It's not about learning Python (syntax) but presents you small and fun riddles. Solving the riddles is based on Python but you can use whatever fits (your calculator, bash scripts, Perl...). After you solved one, you get to see how others have solved it and can discuss the pros & cons of the different ways.

Very nice to get a feel for how things could be done (smart) in Python. This site works especially well if you know a bit about other scripting languages or the commandline, etc.
