Beazley on Generators

[Terry Reedy]

At PyCon2008, David Beazley presented an excellent talk on generators.
Generator Tricks for Systems Programmers
http://www.dabeaz.com/generators/index.html

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.
