用python写一个爬取电影的代码

好的，以下是一个简单的Python爬虫代码，用于从IMDb网站上获取电影信息：

import requests
from bs4 import BeautifulSoup

url = 'https://www.imdb.com/chart/top?ref_=nv_mv_250'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')

movies = soup.select('td.titleColumn')
crew = [a.attrs.get('title') for a in soup.select('td.titleColumn a')]
ratings = [b.attrs.get('data-value') for b in soup.select('td.posterColumn span[name="ir"]')]

for i in range(0, len(movies)):
    movie_string = movies[i].get_text()
    movie = (' '.join(movie_string.split()).replace('.', ''))
    movie_title = movie[len(str(i))+1: -7]
    year = movie[-6:-2]
    place = movie[:len(str(i)) - (len(movie))]
    print(f'{place} - {movie_title} ({year}) - Starring: {crew[i]} - Rating: {ratings[i]}')

这段代码使用了requests和BeautifulSoup库，首先访问IMDb网站上的电影排行榜，然后使用BeautifulSoup解析HTML内容。接着，从HTML中选择所有电影的标题、演员、评分等信息，最后将它们打印出来。
