Python从MP3文件获取id3的方法

def getID3(filename):
  fp = open(filename, 'r')
  fp.seek(-128, 2)
  fp.read(3) # TAG iniziale
  title  = fp.read(30)
  artist = fp.read(30)
  album  = fp.read(30)
  anno  = fp.read(4)
  comment = fp.read(28)
  fp.close()
  return {'title':title, 'artist':artist, 'album':album, 'anno':anno}
