I was going to say something deep about Python here, but again I am not qualified. I program in Python every day - today I was writing a PBSPro hook in Python, and it is supremely adapted for tasks like that. I can also see why the bioinformatics community loves Python.

In reply to Jeff, I am no Julia expert. However I am going to stick my neck out here. Yes, learn Julia. Firstly there is a definite 'buzz' in the Julia community and you encounter science and engineering experts at every turn. Secondly, where I come from. My background is in high energy physics, fr
