Installed python 2.7 in C:\Python27 long time ago. All tools are working with python2. And now I'd like to upgrade it into python 3 in C:\Python3. There are commercial tools like perforce and self-written programs in python that won't work with python 3 automatically. My current PATH is "c:\python27;c:\windows\system32;c:\Windows;C:\Program Files\Perforce;" Working under DOS to validate my tools one by one. Is there a way to quickly switch between python 2 and python 3?
DOS or python scripts
