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 <!--more-->    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()

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()
