[math-fun] Python language

Python seems remarkable in the sense that a typical python program is about 1/5 the length of a corresponding C program (even though C is normally thought of as pretty concise). The question is why. My initial guess at the answer is: Python is a lot like (say) MODULA-3, provided somebody had already written about a million lines of "libraries" of handy subroutines for you. There is nothing inherently concise about python, it is just that you have all these libraries of common tasks so you do not have to code them, you can just use them. Is that guess true?
