如何使用pygame在python中播放音乐？

Question

import pygame
pygame.mixer.init()
pygame.mixer.music.load(file)#any mp3 file
pygame.mixer.music.play()
while pygame.mixer.music.get_busy():
  pygame.time.Clock().tick()

I know this is the code to play the music in python with pygame Can you explain why we use

while pygame.mixer.music.get_busy():
   pygame.time.Clock().tick()

Answer 1

Basically, the play() function is asynchronous .It means it won't wait for a return message to continue. And when the program execution reaches the end, mixer object will be destroyed and the music will stop. To avoid that we use

while pygame.mixer.music.get_busy():
   pygame.time.Clock().tick()

to run the while loop until the music finishes. Then the mixer object will not be destroyed until the music playing finishes. get_busy() method is used to check if the music stream is playing.

Answer 2

from pygame import*
mixer.init()
mixer.music.load('music filename or path with extension .mp3')
mixer.music.play()
