> Basically, the entire data and language processing world works in Python.

Dunno, when I started I learned Stata, but it seemed the big open-source thing was R. Python data stuff was in its infancy. R got huge, then Python got huge. Of course all the underlying libraries are C/C++ or Fortran. Everything does exist in Ruby as well.

But hey, I also just hate Python (find it super complicated to set up, their package managers are terrible, plus find the language inconsistent) so I avoid it at all costs. Would much rather Julia become the de-facto standard.
