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)
