这个是用twisted的task来作, 随便把ipython放到里面, 这样还可以当ipython用.
  # -*- coding: utf-8 -*-

from IPython.Shell import IPShellEmbed
args = ['-pi1','In <\\#>:','-pi2','
<file://%23%3E:','-pi2','/>.\\D.:','-po','Out<
\\#>:','-nosep' <file://%23%3E:','-nosep'/>]
ipshell = IPShellEmbed(args)
ipshell.set_exit_msg('Ctrl-C to exit program')
ipshell.set_banner('Ctrl-D to exit interpreter and continue program')
from twisted.internet import reactor, threads, task
 shell = threads.deferToThread(ipshell) #打开ipython
 player = task.LoopingCall(play_soundfile) #这里是你要打开的程序
 player.start(60*30) #每1800秒播放一次
 #可以用 player.stop() 来中止
reactor.run()
