I think that Numpy with Numba for routines that aren't easily vectorized and or need if statements is just about the perfect combination. https://numba.pydata.o

I think that Numpy with Numba for routines that aren't easily vectorized and or need if statements is just about the perfect combination. https://numba.pydata.org/ https://numba.pydata.org/. Numba functions are very close to C/C++ performance. EDIT: You can write loops explicitly and have OpenMP style for-loops and they are fast.
