Example 1: python multiprocessing

import multiprocessing

def worker1(i):
    print(i, "Process started")

def worker2(i):
    print(i, "Process started")
    
if __name__ == '__main__':
    p = multiprocessing.Process(target=worker1, args("nice",))
    q = multiprocessing.Process(target=worker2, args("nice2",))
    q.start()
    p.start()

Example 2: python multiprocessing

from multiprocessing import Pool

def f(x):
    return x*x

if __name__ == '__main__':
    with Pool(5) as p:
        print(p.map(f, [1, 2, 3]))
