Has there been any official software that allows both the Python 2.x and
3.x releases to coexist on the same OS so that the end-user can easily
switch between them when invoking Python scripts after each has been
installed to their own directories/folders ?
I know of some unoffical solutions, but they require lots of tweaks.
Given the vagaries of the different OSs on which Python can run I am
hoping for some offical solution which will work on any of the most
popular OSs ( Windows, Linux, Mac ).
The situation is so confusing on Windows, where the file associations,
registry entries, and other internal software which allows a given
Python release to work properly when invoking Python is so complicated,
that I have given up on trying to install more than one Python release
and finding a relaible, foolproof way of switching between them. So
although I would like to use the latest 3.x series on Windows I have
decide to stick with the latest 2.x series instead because much software
using Python does not support 3.x yet.
