Python Generator Tricks

The Python programming language's support for generators is described in PEP 255. This article demonstrates a few simple programs which make use of this feature to do some fun stuff like filtering out prime numbers, representing an `infinite' series expansion in a finite way, applying the Euler `accelerator' to make a series converge faster etc. Many of the programs which I describe here have been taken from `test_generators.py' which is available with the Python source distribution.
