You actually want to "brew install pyenv" And then "pyenv install 3.7" or whatever version you're after.

Multiple versions of programming languages don't require docker, containers, or Nix, that is utter insanity.

Not quite utter insanity - isn’t it quite weird that every programming language has its own tool for installing multiple different versions of itself? nvm, pyenv, rbenv, rustup, etc.

Maybe it’s nice to think of a common solution to this!
