I’ve been having a great time using Python Tools for VS. It’s a free download that provides CPython language support in Visual Studio 2010. The intellisense is pretty good (especially for a dynamic language!) and the debugger is useful to have. Having a good IDE is changing the way I view the language. Check out the homepage for a long list of features it supports. One other perk is that because it’s using the VS 2010 shell, it works with my favorite VS 2010 editor extensions.
