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 importos importos.path importImage importhashlib defget_md5(filename): m=hashlib.md5() mfile=open(filename,"rb") m.update(mfile.read()) mfile.close() md5_value=m.hexdigest() returnmd5_value if__name__=='__main__': ipath="E:\\20161019_photo" uipath=unicode(ipath,"utf8") forparent,dirnames,filenamesinos.walk(uipath): md5_list=[] #fordirnameindirnames:#输出文件夹信息 #print"parentis:"+parent #print"dirnameis:"+dirname forfilenameinfilenames: #print"parentis:"+parent #print"filenameis:"+filename #print"md5_listis:" if(get_md5(os.path.join(parent,filename))inmd5_list): os.remove(os.path.join(parent,filename)) else: md5_list.append(get_md5(os.path.join(parent,filename))) #printmd5_list #md5=[]
删除无法打开文件：
#coding=utf-8 importos importos.path importImage importhashlib defget_md5(filename): m=hashlib.md5() mfile=open(filename,"rb") m.update(mfile.read()) mfile.close() md5_value=m.hexdigest() returnmd5_value if__name__=='__main__': ipath="E:\\20161019_photo" uipath=unicode(ipath,"utf8") forparent,dirnames,filenamesinos.walk(uipath): forfilenameinfilenames: 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
