[ale] Slightly OT: System default python version

[Ted W.]

Maybe I'm missing something here but I have to ask why the student isn't
using something like pyenv to configure the version of python and the
modules they need for the particular project. In my admittedly limited
python development experience developing for older systems (CentOS 5 and
6) it was common for the system to have an extremely out of date python
version available in the upstream repositories. Instead of relying on
what I could get from the vendor I would use virtual envs to configure
whatever version I wrote in and install all of the modules necessary on
the target system. Is this not possible or am I missing some piece of
the question?
