将代码生成.py文件放在目录下运行，可以获取该目录的所有mp3文件的信息，需要使用ID3库

import os, sys  from ID3 import *      files = os.listdir(os.getcwd())      for f in files:      x = os.path.splitext(f)      if x[1] == '.mp3':          n = x[0].split(' - ')          author = n[0]          title = n[1]          id3info = ID3(f)          id3info['ARTIST'] = author          id3info['TITLE'] = title          print f+' id3 tagged.'  print 'Done!'
