mp3play有时工作，有时不工作

Question

我正在使用mp3play和google tts api播放机器人语音输出： 代码很简单，但有时是好的，有时是坏的：

def robot_voice(text):
    text=text.split()
    text='+'.join(text)
    url = "http://translate.google.com/translate_tts?tl=en&q="+text
    request = urllib2.Request(url)
    request.add_header('User-agent', 'Mozilla/5.0') 
    opener = urllib2.build_opener()

    f = open("data.mp3", "wb")
    f.write(opener.open(request).read())
    f.close()
    time.sleep(0.5)
    import mp3play
    mp3=mp3play.load('data.mp3')
    mp3.play()
    time.sleep(mp3.seconds())
    mp3.stop()

if __name__=="__main__":
    robot_voice("hello world")

就像我把文件放在一个文件夹里时，它只会发出“你好，世界”的声音，但当我复制粘贴到另一个文件夹中时，会出现错误消息：

Error 277 for "open" data.mp3 "alias mp3_0.395468745176": problem occurred while initializing MCI. Error 263 for "set mp3_0.395468745176 time format milliseconds": The specified device is not open or is not recognized by MCI.
