FreeRADIUS modules python vs python3

Thank you both Alan and Matthew for the response. As an aside, under 
Ubuntu there is a freeradius-python3 package. When I had tried to 
install that one one of our Ubuntu servers, I got dependency issues:

  freeradius-python3 : Depends: freeradius (= 3.0.20+dfsg-3build1) but 3.0.25-2 is to be installed

However, looking at it now, that is maintained by the Ubuntu Developers.

For my current issue on AlmaLinux release 8.5, I think the quickest 
solution for me is rewrite the portions of my python script to work 
under 2.7 until python3 is added to the networkradius packages, then 
switch them to my python3 script. It is still very good to know the 
reasons behind the problems I was running into.

Thank you,
