如何使用“按标签选择”功能下载视频

Question

我尝试从带有python脚本的站点下载视频。 目标是检索div标记'\u 2nCkU'中包含的视频。 python的答案是“无”。你能帮我看看这个问题吗

import requests
from bs4 import BeautifulSoup
username = raw_input('Username : ')
url = 'https://www.website.com/add/' + str(username)

mozhdr = {'User-Agent': 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.0.3) Gecko/2008092417 Firefox/3.0.3'}
requete = requests.get(url, headers=mozhdr)
page = requete.content
soup = BeautifulSoup(page, 'lxml')
div = soup.find('div', {'id': '_2nCkU'})

print(div)
