尝试读取M4B文件时诱变引发错误

Question

这是我关于SO的第一篇文章。我正在尝试在Python 3上使用Mutagen读取m4b文件。这是我正在使用的代码。

for file in os.listdir(workingdir):
    if file.endswith('.m4b'):
      workingdirectory = 'my/directory/'
      commandtoexecute = ""
      metadata = MP4(file)
      print('read')
      xa9ART1 = metadata['\xa9ART']
      xa9nam1 = metadata['\xa9nam']
      xa9alb1 = metadata['\xa9alb']

这是我得到的错误，

我已经在几种音频上尝试过几次，但是对我来说似乎卡住了。我很高兴从这里获得帮助。

谢谢。
