Python爬虫：一个爬取豆瓣电影人像的小案例
从谷歌浏览器的开发工具进入
选择图片右键点击检查
翻页之后发现网址变化的只有start数值，每次变化值为30
Python代码
import requests
from bs4 import BeautifulSoup
import time
import os# 豆瓣影人图片

res = requests.get(url=url, headers="").text
content = BeautifulSoup(res, "html.parser")
data = content.find_all('div', attrs={'class': 'cover'})
picture_list = []
for d in data:plist = d.find('img')['src']picture_list.append(plist)
