I never liked Python’s significant whitespace and the passing of self to nearly every function. So I switched to Ruby a long time ago — which I think is the perfect scripting language that also goes a long way beyond.
I also think a developer needs to learn at least one SERIOUS programming language like Rust, Go, Elixir, or Clojure (the latter two being my personal favorites).
Unfortunately Python still is the go-to to when it comes to data science, math, and ML — due to a proliferation of mature numeric libraries.
