An in-depth look at generators, part 2

Last month, we got started on generators, covering the basics and part of the "Enhanced Generators" capabilities added in Python 2.5 with PEP 342.

We will finish the presentation on generators this month, completing our look at the "Enhanced Generator" capabilities that let you build generators as consumers, rather than just as producers; and looking at the new "yield from" capability that was added in Python 3.3 with PEP 380.

We'll also examine the use of generators as co-routines, where they are not necessarily dealing with streams of data. These can be used to build fibers (http://en.wikipedia.org/wiki/Fiber_(computer_science)) (user threads) and can be used for asynchronous programming.
