Numba is indeed a great library for speeding up Python and also doing other useful things when interacting when external libraries.

For example the "jit compile a single function" feature is gold when you need to pass a function callback pointer into a C library. This is how pygraphblas compiles Python functions into semiring operators that are then passed to the library which has no idea that the pointer is to jit compiled python function:
