Numba

Welcome to Numba

Numba is a translator of Python byte-code to LLVM IR which can then be used to create machine code. It is a dynamic compiler which is used intentionally in places where you might otherwise want to write C/C++, Fortran, or Cython code.

Example:

@numba.vectorize
def sinc(x):
    if x == 0:
       return 0.0
    else:
       return sin(pi*x)/(pi*x)

This will compile to machine code using LLVM and build a NumPy ufunc that uses the corresponding loop for its code.
