python发声应该调用什么库和什么函数,该怎么处理

python发声应该调用什么库和什么函数
我想弄个节拍器,扬声器发声或者调用音频文件都可以,指定每分钟响n次,应该调用什么库和用什么函数
忘指点

------解决方案--------------------
windows下python的标准库中有模块可以播放声音。linux下麻烦一些,要用第三方库。
------解决方案--------------------
这里有http://pysonic.sourceforge.net/,上面给的例子:
Python code
import pySonic
      import time
      
      def finished_stream(source):
        print 'Stream finished playing'
      
      # initialize the audio environment
      w = pySonic.World()
      
      # create two sources
      src1 = pySonic.Source()
      src2 = pySonic.Source()
      
      # load a sound entirely from disk, stream another from disk
      src1.Sound = pySonic.FileSample('short.wav')
      src2.Sound = pySonic.FileStream('long.mp3')
      
      # position the sources in 3D space
      src1.Position = (-0.5, 0.0, 0.5)
      src2.Position = (0.5, 0.0, 0.5)
      
      # register a callback for when the stream finishes
      src2.SetEndStreamCallback(finished_stream)
      
      # register a callback for when the stream finishes
      src1.Play()
      src2.Play()
      
      # just block while we're playing in this example
      while src1.IsPlaying() or src2.IsPlaying():
        time.sleep(1)
