url = 'https://image.baidu.com/search/index?tn=baiduimage&ipn=r&ct=201326592&cl=2&lm=-1&st=-1&fm=index&fr=&hs=0&xthttps=111111&sf=1&fmq=&pv=&ic=0&nc=1&z=&se=1&showtab=0&fb=0&width=&height=&face=0&istype=2&ie=utf-8&word=%E5%B0%8F%E9%BB%84%E4%BA%BA&f=3&oq=xiaohuangren&rsp=0'
html = requests.get(url).text
pic_url = re.findall('"objURL":"(.*?)",',html,re.S)
#match all the clauses,python regular expression for re
i = 0
for each in pic_url:
    print each
    try:
        pic = requests.get(each,timeout=10)
    except requests.exceptions.ConnectionError:
        print "error now for not loading the pictures"
        continue
    string = 'picture\'+str(i)+'.jpg'
    #str()--->conversion to string
    fp = open(string,'wb')
    #establish the file with the name of string,write ability and binary data
    fp.write(pic.content)
    fp.close()
    i+=1
