Great thanks! Another question, if you don't mind. Running python -m pip --version it says: No module named pip which seems odd because python3 -m pip --version shows pip 10.0.1 I guess I was under the assumption that python2 would come with pip installed, was this an incorrect assumption or do I have some kind of conflict?

Python 2.7.15 is my version btw

EDIT: turns out no, in my python27:Scripts folder there is no pip while in my python37:Scripts folder I have pip, pip3.7 and pip3. Which of these can I delete and which one do I want in my python27:Scripts folder? Can I copy and paste?
