While it's definitely useful for production, test, and dev to all match, it's pretty easy to write Python that runs everywhere. In my experience the Python community is a lot better than most at making libraries and extensions work across platform. I've written GUI apps with PyQT where I developed them on Linux and had them run without change on both Windows and OSX. Similarly, I've done some web development on my Mac, deployed to a Linux server, and everything's worked. On the other hand, IMO, developing on Linux is far easier and faster than developing on Windows, so there may be other benefits to using a VM.
