Python in science is more than mere wrapping: it gives you new level(s) of abstractions, unrivalled in any other generic programming language AFAIK. If it were mere wrapping, other languages would have been able to catch up fairly quickly after all.<p>Big parts of numpy (and to a lesser degree pandas) are not in python, but lots of libraries on top of it are mostly python (scikit learn, scikits image, etc.). It is no more wrapping than lisp is wrapping the C VM.
