python批量淘宝网页图片爬取

Question

在家无聊，在家自学爬虫！照着书上的代码敲得，能运行，没有报错，但就是爬取不到图片！求大佬指点！

import urllib.request
import re
key_name = urllib.request.quote("笔记本电脑")
def savefile (data):
    path ="C://Users/Administrator/Desktop/taobao_url.txt"
    file = open(path,"a")
    file.write(data+"\n")
    file.close()
for p in range (0,6):
    url ="https://s.taobao.com/search?q=" + key_name + \
          "&imgfile=&ie=utf8&p4ppushleft=5%2C48"+"&s="+str(p*48)
    datal = urllib.request.urlopen(url).read().decode("utf-8")
    savefile(url)
    pat = 'pic_url":"//(.*?)"'
    img_url = re.compile(pat).findall(datal)
    print(img_url)
    for a_i in range (0,len(img_url)):
        this_img = img_url[a_i]
        this_img_url = "http://"+this_img
        print(this_img_url)
        img_path = "D:\imagetb"+str(p)+str(a_i)+".jpg"
        urllib.request.urlretrieve(this_img_url,img_path)

    我感觉应该是网址的问题，改了以后经常报错然后就改回来了！
