Yes, you should definitely learn more languages. Don't go crazy, but at least 3. You should probably select languages that will enhance what you already are or would like to do. From the suggestions that I've seen here and in the professional context, probably Go, as there are many good arguments for it and in general (since no particular goal was given). For someone coming from Python, Go would be easier to learn, offer something different to your present picture, and it would enhance your resume. Of course, in the non-professional context, you could learn anything. So will give a "shout out" to Vlang (vlang.io). Though in beta, it's a great up and coming language, which is an alternative to Go and C. Vlang would also be a nice addition and smooth transition to or from Go or C.
