Beautiful Soup (suddenly) doesn't get full webpage html

[j.crater]

Hello all,
few months ago I dabbled in Beautiful Soup for first time, so I still lack much understanding of the module and entire subject.
However, the issue I'm having is that B.S. parsed the whole page HTML just fine. And this time, when re-running the same code, I only get partial HTML response, most of the response being lines of JavaScript.

The code is:

import requests
from bs4 import BeautifulSoup

url = "https://www.youtube.com/results?search_query=python"
response = requests.get(url)

soup = BeautifulSoup(response.content, "html.parser")
# print(soup)

Any tip will be much appreciated.
Thanks and best regards,
JC
