You are right, my answer was over-engineered. Instead of speculating about what else needs to be done if one decides to set PYTHONPATH, I should have just advised to use the OS specific method on setting up the "default" Python as Python3 and be with it. Well, unless the dual Python is needed (git-p4 running with the Python different from system "default").
