python删除文件夹下相同文件和无法打开的图片


						前天不小心把硬盘格式化了，丢了好多照片，后来用Recuva这款软件成功把文件恢复过来，可是恢复的文件中有好多重复的文件和无法打开的图片，所以写了两个python的小程序用来解决这个问题

删除相同文件：





#coding=utf-8

 

import os

import os.path

import Image

import hashlib

 

def get_md5(filename):

 m = hashlib.md5()

 mfile = open(filename, "rb")

 m.update(mfile.read())

 mfile.close()

 md5_value = m.hexdigest()

 return md5_value

 

if __name__ == '__main__':

 ipath = "E:\\20161019_photo"

 uipath = unicode(ipath, "utf8")

 

 for parent, dirnames, filenames in os.walk(uipath):

  md5_list = []

  #for dirname in dirnames: # 输出文件夹信息

   #print "parent is:" + parent

   #print "dirname is: " + dirname

  for filename in filenames:

   #print "parent is :" + parent

   #print "filename is:" + filename

   #print "md5_list is : "

 

   if(get_md5(os.path.join(parent, filename)) in md5_list):

    os.remove(os.path.join(parent, filename))

   else:

    md5_list.append(get_md5(os.path.join(parent, filename)))

   #print md5_list

   #md5 = []



删除无法打开文件：





#coding=utf-8

 

import os

import os.path

import Image

import hashlib

 

def get_md5(filename):

 m = hashlib.md5()

 mfile = open(filename, "rb")

 m.update(mfile.read())

 mfile.close()

 md5_value = m.hexdigest()

 return md5_value

 

if __name__ == '__main__':

 ipath = "E:\\20161019_photo"

 uipath = unicode(ipath, "utf8")

 for parent, dirnames, filenames in os.walk(uipath):

  for filename in filenames:

   name ,ext = os.path.splitext(filename)

   if((ext == ".png") or (ext == ".tif") or (ext == ".gif")):

    os.remove(os.path.join(parent, filename))

   else:

    if(ext == ".jpg"):

     try:

      fp = open(os.path.join(parent, filename), 'rb')

      img = Image.open(fp)

     except:

      fp.close()

      os.remove(os.path.join(parent, filename))

     else:

      continue
