[Tutor] PYTHON INSTALLATION PROBLEM

[Richard Damon]

Actually, it says I only have 1 'python', but multiple 'python3'
/usr/bin/python symlinks to a version 2.7 off in /System/Library/Frameworks/

All the versions 3.x only appear as python3 or python3.x

It could well be that they haven't fully removed python2.7 dependencies 
from the system (or maybe better, haven't validated that they have) so 
python means python2 for backwards compatibility.
