   Just wanted to let you know that the usage I described above seems to 
work in all the cases I tried out.

   I added some batch scripts for running a specific Python interpreter 
as a convenience and everything works 'naturally' in our development 
environment.

   Packages can be easily installed to a specific targeted environment 
using for example:
   py243 -m easy_install pip
   py332 -m pip install pytest
[not mentioning tweaks needed for specific ancient Python versions]

   Thank you all for all the suggestions.

   Best regards,
     Jurko Gospodnetić
