Finding up to date info to properly install Python on macOS is a nightmare. Homebrew seems like a nice route but it's hard to find and make sense of their indication about 'unversioned symlinks' e.g. naked 'python', 'pip', etc as opposed to 'python3', etc. The symlinks are actually installed in an odd directory (/usr/local/opt/python/libexec/bin). So I had to add this weird directory to my path.
