About

IronPython is an implementation of the Python programming language running under .NET and Silverlight. It supports an interactive console with fully dynamic compilation. It's well integrated with the rest of the .NET Framework and makes all .NET libraries easily available to Python programmers, while maintaining compatibility with the Python language.

IronPython is an open source project freely available under the Microsoft Public License. You can grab the latest sources by clicking on the Source Code tab at the top of this page or simply by clicking here. Using Team Explorer from inside Visual Studio will give a richer view of source history.
