Python批处理删除和重命名文件夹的实例

1. 删除当前目录下不含有指定文件类型的文件夹

#!/usr/bin/python
# -*- coding: UTF-8 -*-

import sys
import os
import shutil

pwd = os.getcwd()
L = os.listdir(".")
f = open("out.txt", "w")
for dirname in L:
 if os.path.isdir(dirname):
  print("dir name:" + dirname)
  os.chdir(dirname)
  files = os.listdir(".")
  filePreName = "filename"
  extName = "ext name"
  delete = True
  for filename in files:
   print filename
   print >> f, "%s" % filename
   filePreName, extName = os.path.splitext(filename)
   if extName.lower() == ".zip" or extName.lower() == ".jpg" or extName.lower() == ".doc" or extName.lower() == ".pdf" or extName.lower() == ".xls" or extName.lower() == ".gif" or extName.lower() == ".ppt" or extName.lower() == ".iso" or extName.lower() == ".mp3" or extName.lower() == ".wav" or extName.lower() == ".rar" or extName.lower() == ".mkv" or extName.lower() == ".mp4" or extName.lower() == ".bmp" or extName.lower() == ".exe" or extName.lower() == ".docx" or extName.lower() == ".png" or extName.lower() == ".txt":
    delete = False
  os.chdir("..")
  if delete:
   shutil.rmtree(dirname)
   print dirname + " deleted!!!"
   print >> f, "%s" % dirname + " deleted!!!"
  print "--------------------------"
  print >> f, "%s" % "--------------------------"
f.close()1

2. 遍历目录下每个子文件夹，并列出子文件夹下的文件，默认删除含指定类型的文件夹，不包含指定文件类型的，则提示，是否删除或者重命名文件夹

#!/usr/bin/python
# -*- coding: UTF-8 -*-

import sys
import os
import shutil

pwd = os.getcwd()
L = os.listdir(".")
f = open("out.txt", "w")
for dirname in L:
 if os.path.isdir(dirname):
  print("dir name:" + dirname)
  os.chdir(dirname)
  files = os.listdir(".")
  i = 0
  filePreName = "filename"
  extName = "ext name"
  for filename in files:
   print filename
   print >> f, "%s" % filename
   filePreName, extName = os.path.splitext(filename)
   if extName == ".java" or extName == ".js" or extName == ".yml" or extName == ".ejs" or extName == ".svg" or extName == ".sample" or extName == ".styl" or extName == ".class" or extName == ".xml" or extName == ".html" or extName == ".so" or extName == ".OPA" or extName == ".pig" or extName == ".obj" or extName == ".sdb" or extName == ".dll":
    i += 1
  os.chdir("..")
  #整理杂乱的硬盘时，包含这些文件类型的无关文件夹直接删除
  if i >= 3 or filePreName == "HEAD" or filePreName == "master" or extName == "" or (filePreName == "index" and extName == ".html") or extName == ".java" or extName == ".pyc" or extName == ".py" or extName == ".html" or extName == ".HTM" or extName == ".ini" or extName == ".css" or extName == ".so" or extName == ".xml" or extName == ".bin":
    shutil.rmtree(dirname)
    print(dirname + " deleted!!!")
    print "--------------------------"
    continue
  deleteOrNot = raw_input("delete " + dirname + "?(y/n)")
  #除了无关文件夹，其余由“我”决定是删除还是直径重命名文件夹
  if deleteOrNot == 'y':
   shutil.rmtree(dirname)
   print dirname + " deleted!!!"
   print >> f, "%s" % dirname + " deleted!!!"   
  else:
   if deleteOrNot == "":
    print "no change" + dirname
   else:
    os.rename(dirname, deleteOrNot)
  print "--------------------------"
  print >> f, "%s" % "--------------------------"
f.close()

3. 使用子文件夹中第一个文件的文件名作为该子文件夹的名字

#!/usr/bin/python
# -*- coding: UTF-8 -*-

import sys
import os
import shutil
import random

pwd = os.getcwd()
L = os.listdir(".")
f = open("rename.txt", "w")
for dirname in L:
 if os.path.isdir(dirname):
  os.chdir(dirname)
  files = os.listdir(".")
  filePreName = "filename"
  extName = "ext name"
  filename = files[0]
  filePreName, extName = os.path.splitext(filename)
  os.chdir("..")
  os.rename(dirname, filePreName + str(random.randint(1,999)))
  print dirname + "->" + filePreName + str(random.randint(1,999))
  print >> f, "%s" % dirname + "->" + filePreName + str(random.randint(1,999))
f.close()
