掀起异常浪巨蟒

Question

例如，我使用了波模块。

     import wave
     origAudio = wave.open("son.wav",'r')

获得输出

       raise Error, 'file does not start with RIFF id'
       wave.Error: file does not start with RIFF id

我知道这个文件不好，但是我想引发这个异常或者这个错误。

Answer 1

如果你想在提出期望之后继续下去，你必须抓住它：

 import wave
 try:
   origAudio = wave.open("son.wav",'r')
 except wave.Error as e:
   # if you get here it means an error happende, maybe you should warn the user
   # but doing pass will silently ignore it
   pass
