Python multiprocessing continuously spawns pythonw.exe processes without doing any actual work

Question

I don\'t understand why this simple code

# file: mp.py
from multiprocessing import Process
import sys

def func(x):
    print \'works \', x + 2
    sys.stdou         


        

Answer 1

According to the programming guidelines for multiprocessing, on windows you need to use an if __name__ == '__main__':
