Surprisingly Julia. I work in academia (doing PhD in physics) so I'm free to choose tools. I find it to be great also for some side data science projects and general scripting. I was going to learn R and use some but decided that i can call them when necessary and so far it wasn't, so why bother with other languages. I taught some Python but also moved it to Julia (optimization method course). However, there is also some legacy code in (free-format) Fortran and Mathematica/Wolfram Language that i work with so i also use these.
