r=requests.get('https://movie.douban.com/top250')

soup=bs4.BeautifulSoup(r.text,'lxml')

title=soup.find_all('div',class_='hd')
for i in title:
    print(i.a.span.text)

python -m pip install -U urllib3 -i https://pypi.tuna.tsinghua.edu.cn/simple

还有把代码改成这样：

import requests
import bs4
headers = {"user-agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36"}
r=requests.get('https://movie.douban.com/top250',headers=headers)

soup=bs4.BeautifulSoup(r.text,'lxml')

title=soup.find_all('div',class_='hd')
for i in title:
    print(i.a.span.text)

headers就是请求头，不加请求头，可能爬不到，不信的话 ：

import requests
import bs4

r=requests.get('https://movie.douban.com/top250')
print(r.status_code)
soup=bs4.BeautifulSoup(r.text,'html.parser')

title=soup.find_all('div',class_='hd')
for i in title:
    print(i.a.span.text)

结果：
418

也就是说被反爬了

一点反反爬措施都没有的嘛..

import requests
import bs4

headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:78.0) Gecko/20100101 Firefox/78.0'}

r=requests.get('https://movie.douban.com/top250', headers = headers)
