[Python] Multiprocess Pool ID 확인

current process 가 가지고 있는 정보는 아래와 같다.

from multiprocessing import Pool
import multiprocessing

def f(x):
    current = multiprocessing.current_process()
    print('running: {}'.format(current.__dict__))
    return x * x

if __name__ == '__main__':
    with Pool(2) as p:
        print(p.map(f, range(6)))
