This page document how to deal with multiple Python versions on the same system. pyenv is a tool that deals with that.

brew install different Python major and minor versions in Cellar using the following naming scheme:

 Cellar
  ├─ ...
  ├─ python@3.8
  ├─ python@3.9
  ├─ python@3.10
  ├─ python@3.11
  ├─ python@3.12
  ├─ ...

The default Cellar location is /usr/local/Cellar but may differ depending on the brew instance. See:
