用python实现批量重命名文件的代码

# -*- coding: cp936 -*-
import os
path = 'D://图片//'
for file in os.listdir(path):
if os.path.isfile(os.path.join(path,file))==True:
if file.find('.')<0:
newname=file+'rsfdjndk.jpg'
os.rename(os.path.join(path,file),os.path.join(path,newname))
print file,'ok'
# print file.split('.')[-1]
