You're given this warning when you fire up the interpreter (at least in Monterey):

> WARNING: Python 2.7 is not recommended. This version is included in macOS for compatibility with legacy software. Future versions of macOS will not include Python 2.7. Instead, it is recommended that you transition to using 'python3' from within Terminal.

They have deprecated Ruby (and even Perl), as well. I think it’s still there (I use SwiftLint and Jazzy), but its days are numbered.
