结合两个函数来执行

Question

我正在尝试使用asciimatics和winsound.Beep来创建一个同时播放蜂鸣音的视觉效果，我有两个功能需要同时执行，这样当我的asciimatics视觉开始播放时，蜂鸣音就会发出。请帮帮忙。

Answer 1

from threading import Thread

def f():
    print("f")

def g():
    print("g")

def f_and_g_at_once():
    t1 = Thread(target=f)
    t2 = Thread(target=g)
    t1.start() # returns immediately after the thread starts
    t2.start()

f_and_g_at_once()

或

from multiprocessing import Process

def f():
    print("f")

def g():
    print("g")

def f_and_g_at_once():
    p1 = Process(target=f)
    p2 = Process(target=g)
    p1.start() # returns immediately after the process starts
    p2.start()

# This condition is important, see:
# https://docs.python.org/3/library/multiprocessing.html#the-spawn-and-forkserver-start-methods
if __name__ == "__main__":
    f_and_g_at_once()

什么是更好的取决于上下文，但在您的情况下，threading变体将是更好的选择。
