Cython has prange. It replaces range() in the for loop but runs the loop 
body in parallel using openmp:

from cython.parallel import prange

cdef int func(Py_ssize_t n):
     cdef Py_ssize_t i

     for i in prange(n, nogil=True):
         if i == 8:
             with gil:
                 raise Exception()
         elif i == 4:
             break
         elif i == 2:
             return i

This is an example from the cython documentation:
