I vote for itertools. You'll learn a lot of functional programming style from using this code, though perhaps not from reading the source.

For a good module-by-module tutorial, try Doug Hellmann's Python Module of the Week. I also like the python programming style/practices explored and developed at WordAligned. I also like Peter Norvig's code, especially the spelling corrector code and the sudoku solver.

Other cool modules to learn: collections, operator, os.path, optparse, and the process/threading modules.
