Its a bit more nuanced because we are all people who know varying degrees of code and have already "been there," so to speak.
To learn Python I'd argue you'd have to know a bit (read: not much) of the UNIX environment and args before you jumped in, and my difficulty with it in college was that I had only learned from compiled languages with all of the libraries pre-built for me.
However, I would have bypassed all of those difficulties if I had learned how to be a "sudoer" from the beginning.
I think going the HTML --> CSS --> Vanilla Javascript route could possibly get kids coding before they lose their first teeth. Kids are already very savvy with their mobile browsers.
