I made the opposite choice 20 years ago, and could say the same about my choice. But I wouldn't because realistically language choice is largely about what makes you happy. A good dev needs to be a polyglot anyway.
And I chose Ruby about the same amount of time ago, spent 18 years or so writing that professionally, and now write Python for a living. They’re not that dissimilar, if you can use Ruby you’ll pick up Python pretty quickly. (You will however swear profusely now and again as you encounter another incredibly clunky bit of syntax)
