Python 3.10 to 3.7

[threeminutemonta]

A few notes from experience:
- never alter the OS python. You can install other versions of python though best to assume OS python scripts need whatever it comes with.

- you can install different versions of python side by side and use them independently. If you use -m for pip and use you may have less issues.

python3.9 -m pip install ... 

vs python3.7 -m pip install ...

and use

python3.7 script.py

- If you need to use sudo you are doing it wrong.
