python目录与文件名操作例子


            1、操作目录与文件名





#!/usr/bin/env python

#-*- coding: utf-8 -*-



import os,re

import 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 re

pattern = re.compile("1ABC")

pattern.search(var)
