Which version of python goes well with tkinter?

[Barrowman]

In an earlier post I said I did the following:

cd /usr/bin
sudo rm python3
sudo ln -s python3 python3.6
sudo pip3 install wxpython

That has fixed it. Be aware that the install takes a while - about 15 minutes on my 2.8GHz processor with 16 Gig ram

But it has had a bad effect overall to my system as most things would no longer work. I am guessing this has to be something with an incompatibility with them and 3.6 because after a reboot I had to get into a virtual terminal to put it back and everything was back to normal.
