批量重命名文件 Python

import os
import glob
import re
path="C:/test" # 批量化的初始位置
fileHandle = open ( 'C:/test/test.txt', 'w' ) #log记录rename的信息

def getthefile(path):
for oldfn in glob.glob( path + os.sep + '*' ):
if os.path.isdir( oldfn):# 查询是含有子目录
getthefile( oldfn)
else:
if re.search(' ', oldfn):
fn=renamefile(oldfn)
if os.path.exists(fn):
index=1
while True:
filelist=fn.split('.')
fn="%s%s%s.%s"%(filelist[0],"_",index,filelist[1])
if os.path.exists(fn):
index=index+1
continue
break

fileHandle.flush()
continue
