python脚本：批量重命名文件名

　　最近在跟着师姐做一个项目，需要不断地抠样本，用于学习训练。每次扣完样本后都需要重新批量命名一下，虽然Windows7可以批量重命名，但是文件一多的时候就很容易发生资源管理器卡死了。。。因此，决定写个python的脚本，节省下以后重命名的时间。

　　代码

#!\usr\bin\env python
# -*- coding: utf-8 -*-
# Author: PZX
# FileName: batchrename.py
# Function: 批量命名某一文件夹下的文件名

import sys
import os

def UsePrompt():
    #如果省略path，则path为当前路径
    print 'Useage: batchrename.py [path] newfilenames'
    sys.exit()

def BatchRename(path, pattern):
    #设置路径
    os.chdir(path)
    fileList = os.listdir(path)
    
    dotIndex = pattern.rfind('.')
    fileName = pattern[ : dotIndex]
    fileExt = pattern[dotIndex : ]
    genNum = 0
    for fileItem in fileList:
        fileFullName = fileName + ' (' + str(genNum) + ')' + fileExt
        os.rename(fileItem, fileFullName)
        print (fileItem + ' => ' + fileFullName) 
        genNum += 1

def main():
    if len(sys.argv) == 3:
        path = sys.argv[1]
        pattern = sys.argv[2]
    elif len(sys.argv) == 2:
        path = os.getcwd()
        pattern = sys.argv[1]
    else:
        UsePrompt()
    confirm = raw_input('Confirm(y|n): ')
    if confirm == 'n':
        sys.exit()
    BatchRename(path, pattern)
    
if __name__ == '__main__':
    main()　　

　新增：

　　添加撤销上次批量重命名功能。使用方法：batchrename.py /r
