Python Tools for Visual Studio
Python Tools for Visual Studio turns Visual Studio into a Python IDE. It's a free & open source plug-in for Visual Studio 2010 from Microsoft's Developer Division. PTVS enables developers to use all the major productivity features of Visual Studio to build Python code using either CPython or IronPython and adds new features such as using High Performance Computing clusters to scale your code. Together with one of the standard distros, you can turn Visual Studio into a powerful Technical Computing IDE...
Note: PTVS is not a Python distribution; it works with your existing Python/IronPython installation to provide you an integrated editing and debugging experience.
