IronPython
IronPython is JimHugunin's implementation of Python on the .NET CLR.
The project has a workspace where you can get news and download the latest version.
- Stable Version is 1.1.2 (targeting Python 2.4)
- Developers Version is 2.0 RC1 (targeting Python 2.5)
Version 2 (which uses the Dynamic Language Runtime, a framework for writing dynamic languages for .NET which was abstracted out of IronPython 1) is part of Silverlight 2. This means that IronPython can be used for client-side scripting in the browser.
Mozilla are working on porting the DLR (well, the underlying Core CLR that it uses in fact) to run on their Tamarin JIT. This should mean that IronPython will also run in future versions of Firefox. (See IronMonkey).

- Silverlight!

A useful resource for IronPython code examples, is the IronPython Cookbook.
A book that introduces core concepts of IronPython programming using a .NET–centric approach is Pro IronPython.

Other Python-Like Languages for .NET/Mono
Some other Python-like languages for .NET and Mono include:
BooLanguage - Syntax is very similar to Python's, yet the language is statically compiled. It implements many features that have been suggested for Python3.0. See Gotchas for Python Users for specific comparisons between boo and CPython.
Accessing .NET from CPython
Python for .NET is the reverse of IronPython, it lets you access .NET assemblies from CPython.
