IronPython is a Microsoft sponsored open source implementation of the Python dynamic programming language on Microsoft’s .NET framework and version 1.0 was formally released yesterday:
IronPython 1.0 Ships!!
IronPython is a project that implements the dynamic object-oriented Python language on top of the CLI. IronPython is both well integrated with the .NET Framework and is a true implementation of the Python language. .NET integration means that this rich programming framework is available to Python developers and that they can interoperate with other .NET languages and tools. All of Python’s dynamic features (such as, an interactive interpreter and the ability to dynamically modify objects) are available.
Microsoft’s Jim Hugunin recounts the history of its development at his blog and you can download IronPython 1.0 here.
