Python多处理不调用函数

Question

I'm trying to get this code to work, and it looks like update isn't getting called. Nothing is printed to the console with this code, why?

from multiprocessing import Process

def update():
    print("hi")

if __name__ == '__main__':
    p = Process(target=update, args=())
    p.start()
    p.join()

Answer 1

从命令行运行程序，python idle无法正确处理此操作，如此处所述

Answer 2

Sorry for the stupid answer, but maybe you do not have time to see the output in stdout? Try running the script from the command line, like this: c:\\<script location>\\script.py

UPD: riscnotcisc said true.
