1. 刪除當前目錄下不含有指定文件類型的文件夾

#!/usr/bin/python# -*- coding: UTF-8 -*-import sysimport osimport shutilpwd = 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. 遍歷目錄下每個子文件夾，并列出子文件夾下的文件，默認刪除含指定類型的文件夾，不包含指定文件類型的，則提示，是否刪除或者重命名文件夾

#!/usr/bin/python# -*- coding: UTF-8 -*-import sysimport osimport shutilpwd = 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("..")  #整理雜亂的硬盤時，包含這些文件類型的無關文件夾直接刪除  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)")  #除了無關文件夾，其余由“我”決定是刪除還是直徑重命名文件夾  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()
