Playing midi on Pygame

The following code will play music.mid located in the current directory

import pygame
pygame.init()

pygame.mixer.music.load("music.mid")
pygame.mixer.music.play()

If you have a simple program that exits after the play instruction, music playback will stop.

you should add the following two lines:

while pygame.mixer.music.get_busy():
    pygame.time.wait(1000)

to prevent the program from exiting before the music has finished playing.
