How can one get a direct link to a YouTube video in Python?

Question

YouTube

Hi everybody. There are programs that, if you feed a link to a video on YouTube, VK, they can get a direct link to the video without working with the API. I.e. They kind of launch a video and look where the resource redirects them and in this way get a direct link. FireBug works in much the same way. Can you please tell me how this can be done in Python?

look, analyze, everything is visible there quickly
yt-subs.afut.in immediately and the subtitles are extracted
to Python - you get the page (urllib, requests, curl - it doesn’t matter), you find the desired URL with regclares or xpath - profit
