本文实例讲述了python使用PyGame播放Midi和Mp3文件的方法。分享给大家供大家参考。具体实现方法如下：

				?

									''' pg_midi_sound101.py

									play midi music files (also mp3 files) using pygame

									tested with Python273/331 and pygame192 by vegaseat

									'''

									import pygame as pg

									def play_music(music_file):

									  '''

									  stream music with mixer.music module in blocking manner

									  this will stream the sound from disk while playing

									  '''

									  clock = pg.time.Clock()

									  try:

									    pg.mixer.music.load(music_file)

									    print("Music file {} loaded!".format(music_file))

									  except pygame.error:

									    print("File {} not found! {}".format(music_file, pg.get_error()))

									    return

									  pg.mixer.music.play()

									  # check if playback has finished

									  while pg.mixer.music.get_busy():

									    clock.tick(30)

									# pick a midi or MP3 music file you have in the working folder

									# or give full pathname

									music_file = "Latin.mid"

									#music_file = "Drumtrack.mp3"

									freq = 44100  # audio CD quality

									bitsize = -16  # unsigned 16 bit

									channels = 2  # 1 is mono, 2 is stereo

									buffer = 2048  # number of samples (experiment to get right sound)

									pg.mixer.init(freq, bitsize, channels, buffer)

									# optional volume 0 to 1.0

									pg.mixer.music.set_volume(0.8)

									try:

									  play_music(music_file)

									except KeyboardInterrupt:

									  # if user hits Ctrl/C then exit

									  # (works only in console mode)

									  pg.mixer.music.fadeout(1000)

									  pg.mixer.music.stop()

									  raise SystemExit
