How can I play a sound while other lines of code execute simultaneously?

问题

I want my code to do this, but with music playing in the background:

import time 
while True:
    print ('ligma')
    time.sleep(1.5)

I tried this:

import time 
import winsound
while True:
    print ('ligma')
    time.sleep(1.5)
    winsound.PlaySound("dank", winsound.SND_ALIAS)

but, it repeats the sound then repeats the word. I am expecting it to repeat the word and play the sound at the same time.

回答1:

You need to play the sound on another thread, so your other code can be executing at the same time.

import time
import winsound
from threading import Thread

def play_sound():
    winsound.PlaySound("dank", winsound.SND_ALIAS)

while True:
    thread = Thread(target=play_sound)
    thread.start()
    print ('ligma')
    time.sleep(1.5)

EDIT: I have moved the thread declaration into the loop. My initial answer had it created outside of the loop, which caused a RuntimeError. Learn more here: https://docs.python.org/3/library/threading.html#threading.Thread.start

It's called asynchronous sound, and the winsound.SND_ASYNC flag on PlaySound will let you play a sound while your code continues to execute:

winsound.PlaySound("dank", winsound.SND_ALIAS|winsound.SND_ASYNC)

From memory, this will give you a single sound channel i.e. playing other sounds will cut off any currently playing sounds. If more concurrent playback is required, something like PyGame is required.
