抱歉,之前没看到评论,这样可以吧?

import requests
import re


url = 'https://tieba.baidu.com/p/6503175911'
headers = {
    'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36'
}

request = requests.get(url,headers=headers)
html = request.text
contents = re.findall(r'.+style="display:;">(.+?)</div>',html)
for i in range(len(contents)):
    contents = contents.strip()
print(contents)
