Why doesn't bs4 ( BeautifulSoup ) see the [ div class="h1" ] element?

Question

Python

Hello, here is the following:
for example, there is a page:
www.irk.gov.ru/events/news/detail.php?ID=19587
news title - in

<div class="h1">В своих избирательных округах проведут ближайшую неделю депутаты Законодательного Собрания </div>

However, running the code:

import requests
from bs4 import BeautifulSoup
import sys, traceback 


def main():
    try: 
        r = requests.get('http://www.irk.gov.ru/events/news/detail.php?ID=19587',  'html.parser')
        soup = BeautifulSoup(r.content, 'html.parser')
        for i in soup.find_all('div', class_="h1"):
            title = i.text
            print(title) #(если  print(i) - то <div class="h1">Просмотр новости</div>)
            input()
    except Exception:
        print(traceback.format_exception(*sys.exc_info())[1])
        input("End ")

gives some kind of "News view", which is not even in the source code of the page

Answer 1

It is possible that this div is filled with a script at the moment the page is loaded into the browser, then at the time of your request the div is still empty and contains the default value "View News"
