I always find myself needing a control template so I can customize one of the WPF controls. I used to fire up Expression Blend to get it, and then realized I could write a little IronPython code to do it. Paste this code into the IronPython 2.0 or 2.6 console to see it work!
Pyevolve aims to be a "complete genetic algorithm framework written in pure python". The Pyevolve blog has benchmarked some genetic algorithms code running on all the major Python implementations: CPython 2.6 & 2.5, Unladen Swallow, IronPython, PyPy and Jython. IronPython 2.6 comes out slower than CPython (and Unladen Swallow) and faster than PyPy and Jython.
adodbapi is a Python module for working with Microsoft ADO for connecting to databases and datasources. adodbapi is compatible with the Python DB-API 2.0 specification, meaning that it can be used by any DB-API compatible code. Thanks to the work of Vernon Cole, adodbapi now passes all tests when run on both CPython and IronPython.
