However you have little control over the version number you run, as Apple updates it only with new Xcode releases. Python 3 is the one we’re going to use for modern Python development. In this case you can run python3 on your terminal to check the exact version installed, and if it’s recent enough you might be already set up. If you install Xcode, the Apple Development IDE, it installs Python 3 in /usr/bin/python3.
MacOS installs Python 2 (outdated) by default, for compatibility reasons, making it available as /usr/bin/python.
