How to package a Python command line app?

[Manfred Lotz]

The are many possibilities to package a Python app, and I have to admit
I am pretty confused.

Here is what I have:

A Python command line app which requires some packages which are not in
the standard library.

I am on Linux and like to have an executable (perhaps a zip file with a
shebang; whatever) which runs on different Linux systems.

Different mean
- perhaps different glibc versions
- perhaps different Python versions

In my specific case this is: 
- RedHat 8.4 with Python 3.6.8
- Ubuntu 20.04 LTS with Python 3.8.10 
- and finally Fedora 33 with Python 3.9.9


Is this possible to do? If yes which tool would I use for this?
