Python多处理不调用函数 [英] Python multiprocessing not calling function

问题描述

我正在尝试使此代码正常工作，并且好像没有调用update.此代码没有打印到控制台，为什么?

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()

推荐答案

从命令行运行程序，python idle无法正确处理此问题，详情请参见

Run your program from the command line, python idle doesn't deal with this correctly as detailed here
