Can I make different co= mmands for invoking python 2 and Python 3? I am using Windows 7 and use Win= dows Powershell as an alternative to the linux terminal. Any suggestions ab= out how to do that instead of breaking all my code at once? Yep! And in fact, Python 3.3 includes a launcher that makes it fairly easy. Just install another version, and then check this out: http://docs.python.org/3.3/using/windows.html#launcher You can use a Unix-style shebang to specify which Python version some script depends on.
