There are other python implementations like pypy which includes a JIT (Just In Time compiler). There are other jit which can run with official python (cpython) like numba (not all code can be optimized, but if you only need optimize your hot code path).
You can use a superset language of python called cython that generate C code. It can be used to generate C bindings or fast python (for cpython) modules implemented in a python like code.
How many languages on this list are ranked WELL above python, yet extraordinarily easy, syntactically, to write? A lot. How many of them have FFIs to use python's great libraries? Virtually all of them.
