我可以通过在开发人员工具中转到网络面板来下载视频。但是我该如何使用python +硒呢？

您需要获取文件托管的URL，并使用requests下载并将其写入文件。像这样

import requests

... <selnium code to parse web page>

def save_vid(name=None, url=None):
    if not name:
        name = 'video.mp4'

    user_agent = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36'
    response  = requests.get(url, headers={'User-Agent': user_agent})

    with open(name, 'wb') as f:
        print ("Donloading chunck")
        for chunk in response.iter_content(chunk_size=255): 
            if chunk:
                f.write(chunk)
    print("Done")

专门针对reddit，获取了视频的来源

 --> <source src="https://v.redd.it/l67upl0tug921/HLSPlaylist.m3u8" type="application/vnd.apple.mpegURL">
</video>

获取视频ID

来自src="https://v.redd.it/l67upl0tug921/HLSPlaylist.m3u8， ID = l67upl0tug921

托管视频https://v.redd.it/l67upl0tug921/DASH_4_8_M

使用上面的功能下载。

注意：请确保在请求中使用用户代理+僵尸程序延迟1秒（根据reddit）
