Ask HN: Which language would you study if you started going to university now?

I'm going to university next year and I'll have to choose between a Java class, .NET (so C#?) class and C++ class. Background: It's a bioinformatics major (CS minor), but I'm interested in programming in general, data science, etc. (and Python rules there, anyway). I think they'll going to teach us Python anyway + on of those three languages.

Which one of those three would you choose? Also, a bonus question, if you didn't have to choose one from those three, which language would you choose to study?
