代码如下:


# encoding:utf-8

##
# 文件名如:
# 下吧.mp3
##
import os,re

fs=os.listdir('xb')
for f in fs:
 ######方法一:partition获取无用字符
 #1.将文件名以'['符分为3部分
 #ls=f.partition('[')
 #2.ls[0]为需要文件名,因此获取ls[1:]
 #dirtystring = ''.join(ls[1:])
 #3.开始替换
 #newname=f.replace(dirtystring, '') + '.mp3')
 #os.rename('xb/' + f, newname)

 ######方法二:正则获取无用字符
 dirtymatch = re.search(r'\[.*?\]', f)
 if dirtymatch:
  dirtystring=dirtymatch.group(0)
  newname=f.replace(dirtystring, '') + '.mp3'
  os.rename('xb/' + f, newname)

 #注意:可以直接用re.sub方法进行正则替换掉文件名中不需要字符
