These are not "simple" computations.

Any compiled language (Fortran, C, C++, typically) will probably go much
faster than any interpreted/bytecode-based language (like python or
perl, anything that does not use a jit).

I have never seen any serious use of python for numerical computations
without use of numpy/scipy, which is basically a python wrapper around
compiled libraries. You probably should consider such a combination.

No surprise.

I have no idea on what this could be useful for, but it took me a few
seconds to type "python sendkeys" and get some interesting results.
