1、操作目录与文件名

#!/usr/bin/env python#-*- coding: utf-8 -*-import os,reimport shutil import time

用listdir搜索

def search_OFD_old(my_pattern, diretory): try: names = os.listdir(diretory) except os.error: print "error" return for name in names: fullname = os.path.normpath(os.path.join(diretory, name)) if os.path.isfile(fullname): result = my_pattern.search(name) if result and name.lower().endswith("txt"): shutil.copy(fullname, dest_dir) elif os.path.isdir(fullname): search_OFD(my_pattern, fullname)

用walk函数搜索

def search_OFD(my_pattern, diretory): for root,dirs,files in os.walk(diretory): for filename in files: result = my_pattern.search(filename) if result and filename.lower().endswith("txt"): fullname = os.path.join(root, filename) shutil.copy(fullname, dest_dir)

目录不存在，则创建：

if not os.path.isdir(dest_dir): os.makedirs(dest_dir)

匹配名称

import repattern = re.compile("1ABC")pattern.search(var)
