Mint 20 and python development

Thank you Chris, that is the issue, Mint20 will insist on using Python 3 even after i had 5 or 6 Python versions installed and the links pointing to them set up, still some stuff would not work.
There is no way of knowing if something will work or not without testing, it will depend on what that code will be using, but in general so far it will have issues with importing modules, especially QT5 modules.
My advice, do not waste time testing this, Python3 messed up plenty of stuff and the internet is full of people having issues with it, installing 19.3 with RT kernel and LinuxCNC takes about 20 to 30 minutes on an oldish PC, takes about 3.5 minutes on my new PC.
Personally i am reverting back for a while till things get sorted out for my testing machines, using Mint 20 on my personal machines and leaving 19.3 on client machines.

Tom says that you can run a precompiled python2 version of linuxcnc on mint 20 (I haven't tried that )

Yes it does, the Stretch version and the dev, but dev will require some packages to be installed.
Have not tried the Buster version yet, i wonder why ?
