Scala is one of the only languages that I've missed after using Python for the past few years. (When I look for jobs, I mostly look for Python and Scala jobs rather than other languages I've worked in.)

Other comments point out that you should try to dig deeper into python. That's fair. But if you've only worked in a couple languages, learning a new language will give you more perspective on the languages you already know.

Learning any other language will probably be helpful, but Scala is an easy recommendation to make. It'll force you to learn new things, and it's a pleasant language to work in once you get used to it.
