I decide to run a few applications in Racket, but the application  requires number crunching. I install the Jit Racket in the hosting service, and call it from my dynamic generated page. My programs will run almost at the speed of optimised C.

PyPy is an alternate implementation of Python written in Python with
JIT compilation.  It is compatible with various web frameworks.
You'll find it at pypy.org.

Why not just use emacs?  It has a python mode.

The pillow library (successor to the defunct Python Imaging Library)
is probably the best known.  It's not a C library, but it is an
extension library, meaning it is a Python library written in C.

Try SymPy.
