Which language is better for data science?

Question

Which language is the most preferable one in data science programming?

python
C++
MATLAB
or What?

which one should I concentrate on more?

Answer 1

I'd say Julia. it's a mix of Python and c++ but also can call on python packages and has a Matlab like function extension.
But, it's newer so you will have to learn it a bit on your own.

(It's actually quite decent though. in Julia box, you can use ? to pull up help and look up anything you don't understand, recursive search functions for history, etc.)
