Pyquery爬取豆瓣电影Top250

---

解析网页获取到电影排名，url.评分，星级数据

代码如下：

import requests
from pyquery import Pyquery as pq

# 这里做一个循环，因为每页都展示25部电影信息
for page in range(0, 250, 25):
    url = 'https://movie.douban.com/top250?start={}'.format(page)
    headers = {
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36'
}
html = requests.get(url, headers=headers).text

html = pq(html)
for item in html('.item').items():
    num = item.find('.pic em').text()
    title = item.find('.title').html()
    link = item.find('.pic a').attr('href')
    star = item.find('.rating_num').text()
    file = open("爬取成功.txt", "a", encoding="utf-8")
    file.write('
'.join([num, title, star, link]))
    file.close()
