How to install Python on a Mac

[snippsat]

I have PYENV installed. Does it impact what you proposed above?

Then you can use pyenv,look at pyenv Simple Python Version Management.
So have done setup for pyenv correct?
For Mac wiki.

Then is my last post,update pyenv and now the last version is pyenv install 3.8.5.
Set it as global(system wide) then use it.
