Java could have libraries almost as easy to use as python, but doesn't. However, some things can't be as easy as in Python, such as sympy, which does symbolic processing of in-python expressions (differentiation, integration etc). I actually don't find python easy to use - every time I use it, I have to look up how to do for loops (what? range? zero-based? does it include the last one?), and the docs don't have links for arguments (even though they require specific types), because no static types. But the libraries absolutely are easy to use. And because many are written in C (unlike most of Java's librries), you're arguably running C.
