python删除文件夹下相同文件和无法打开的图片

这篇文章主要为大家详细介绍了python删除文件夹下相同文件和无法打开的图片，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

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
