Using python multiprocess outside the main script

python python-3.x python-multithreading python-multiprocessing

Multiprocessing doesn't have to run within the __main__ block, __main__ block is only used if the file is ran via python filename.py.

So if you did:

m1.py:

from multiprocessing import Pool    def f(x):    return x^2def f2():    p = Pool(5)    p.map(f, [1,2,3,4,5])

m2.py:

from m1 import f2if __name__ == '__main__':    f2() # this would run multiprocessing code

and then call python m2.py, your code would run correctly, with mp.
