The Python Cookbook is a collection of recipes for doing various tasks in a Pythonic fashion. I actually sat down and read through most of it (I cheated and skipped the parts on Windows and Tk), so that I could get a better idea of what pythonic code looks like. I definitely learned quite a bit, and I'm sure I'll be turning back to some of the recipes as I am writing more code. There's also the online version, but it was much easier to read all the code and discussion in the paper version. Of course, the online version has evolved past the paper version, so both versions have their uses. Recommended.
