many versions on python on linux

[metulburr]

i would like to setup as many installed versions of python

You are not limited to whatever that linux distro's repo has available. You can just download every python version you want from python.org and compile them from source. In theory you can have every single version ever built if you really wanted to.

After you download each python version, change directory to that download directory and execute

./configure
make

and there will be a python executable named python for that version downloaded in that directory. And you just repeat the process with every version you want. And to run that version ./python if your in that directory, otherwise the path to that directory.

I can honestly say, that most linux users would just build it from source as they do with everything else.
