I was doing a job interview and the manager asked me why I choose python over other languages like R, like if I tough that python was the best language or what? I answered that python is not the best language for anything, for any job you want there's a better language, but python is the second best one for everything, so it offers a flexibility that no other language can. Like in my actuarial sciences MBA, all the professors use R, for 99% of they do I have an equivalent library in python, for the 1% that don't I can use rpy2 and run R code directly in python. Guess they liked my answer because I was approved and I'm about to start there in October.
