At PyCon2008, David Beazley presented an excellent talk on generators.
Generator Tricks for Systems Programmers

At PyCon2009, he followed up with another talk on more advanced
generator usage, which Guido commended on the python-ideas list:
A Curious Course on Coroutines and Concurrency

I have just started (this one will take more than one sitting ;-) but it
looks just as good.
