糗事百科是一个静态网页，对于爬取网站视频还是比较简单的~

import requests
    import re
    import time
    def download(url, title):
        path = 'D:\\python\\demo\\糗事百科\\短视频\\' + title
        response = requests.get(url=url)
        with open(path, mode='wb') as f:
            f.write(response.content)
    
    for page in range(1, 14):
        time.sleep(1)
        print('==========================================正在保存第{}页视频===================================================='.format(page))
        url = 'https://www.qiushibaike.com/video/page/{}/'.format(page)
        headers = { 
            'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.138 Safari/537.36'
        }
        response = requests.get(url=url, headers=headers)
        lis = re.findall('<source src="(.*?)" type=', response.text, re.S)
        for li in lis:
            video_url = 'https:' + li
            title = li.split('/')[-1]
            download(video_url, title)
            print(video_url)
