I seem to have all of Python 2.7, 3.2, 3.3, and 3.5 installed on my server just from APT. I happen to only use 2.7, but I certainly don&#x27;t see what use I would have for some crazy tool to manage versions of Python for me... if the project needs Python exactly 3.2 for some specific reason I can just run python3.2 instead of python3.5 or python3.
