python爬取豆瓣电影top250代码

以下是使用Python爬取豆瓣电影Top250的示例代码：

import requests
from bs4 import BeautifulSoup

url = 'https://movie.douban.com/top250'

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}

movie_list = []

for i in range(0, 250, 25):
    res = requests.get(url, headers=headers, params={'start': str(i)})
    soup = BeautifulSoup(res.text, 'html.parser')
    movies = soup.find_all('div', {'class': 'info'})
    for movie in movies:
        title = movie.find('span', {'class': 'title'}).text
        rating = movie.find('span', {'class': 'rating_num'}).text
        quote = movie.find('span', {'class': 'inq'}).text if movie.find('span', {'class': 'inq'}) else None
        movie_list.append({'title': title, 'rating': rating, 'quote': quote})

for movie in movie_list:
    print(movie['title'], movie['rating'], movie['quote'])

这段代码使用了requests库和BeautifulSoup库来获取网页内容和提取页面信息。循环遍历每一页，找到每部电影的标题、评分和简介（如果有的话），并将它们保存在一个列表中。最后，打印出每部电影的信息。
