python 爬取美女图片的练习
主要使用 xpath 定位获取 图片的链接
本次练习使用到os库 ，lmxl库 ， requests库

import requests
from lxml import etree
import os
if name == ‘main’:
headers = {
‘user-agent’: ‘Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/93.0.4577.82 Safari/537.36’
}

url = r"https://www.tupianzj.com/meinv/mm/jurumeinv/"
respond= requests.get(url=url,headers=headers) #发起请求
respond.encoding = 'gbk' 
res = respond.text


tree = etree.HTML(res)
title_list = tree.xpath('//*[@id="container"]/div/div/div[2]/div[2]/div[2]/dl/dd/ul/li')   # 元素定位
if not os.path.exists('./picture'):
    os.mkdir('./picture')
for i in title_list:
    res = i.xpath('./a/img/@src')[0]
    a = i.xpath('./a/img/@alt')[0] + 'jpg'
    img_data = requests.get(url =res,headers=headers).content
    img_path = 'picture/'+ a
    with open(img_path,'wb') as fp:
        fp.write(img_data)
        print(img_data,'下载成功')

    print(res,a)
