Return Value Of Multiprocessing And Extract It As An Input Of Another Function In Python

from multiprocessing import Pool a=[1,2,3,4,5,6] def func1(a): return a**2 def func2(a): x= np.zeros(1) for i in a: x += i return x if __name__ == '__main_

Solution 1:

Maybe you are looking for something in this direction:

import multiprocessing as mp
import numpy as np

def func1(n):
    return n ** 2

def func2(a):

    pool = mp.Pool(mp.cpu_count())

    results = pool.map(func1, a)

    pool.close()
    pool.join()

    print(results)
    # [1, 4, 9, 16, 25, 36]

    x = np.sum(results)
    return x


if __name__ == "__main__":
    a = [1, 2, 3, 4, 5, 6]
    
    out = func2(a)
    print(out)
    # 91
