批量替换文件名中重复字符：

# -*- coding: UTF-8 -*-import ospath = raw_input("请输入文件夹路径:")oldname = raw_input("输入被替换的字符:")newname = raw_input("输入新的字符(如为空直接回车):")for file in os.listdir(path):    if os.path.isfile(os.path.join(path,file))==True:         if file.find(oldname) > -1:             new_name=file.replace(oldname,newname)             os.rename(os.path.join(path,file),os.path.join(path,new_name))                          print 'OK! ',new_name

 

 按文件顺序重新以序号命名：

# -*- coding: UTF-8 -*-import os path = raw_input("请输入文件夹路径:")i = int(raw_input("开始序号:"))for file in os.listdir(path):    if os.path.isfile(os.path.join(path,file))==True:        new_name = file.replace(file,"%d.jpg"%i)        os.rename(os.path.join(path,file),os.path.join(path,new_name))        i+=1        print 'OK! ',new_name
