response = requests.get('https://www.nytimes.com/',headers={'User-Agent': 'Mozilla/5.0'})
soup = bs4.BeautifulSoup(response.text,'lxml')
soup.body.get_text(' ', strip=True)

Для анализа HTML-тегов со статических веб-сайтов вы можете использовать такие вещи, как BeautifulSoup, чтобы получить содержимое определенных HTML-тегов и атрибутов , <p> таких как <div> , <aside class="green"> и так далее.
Но имейте в виду, что некоторые сайты могут потребовать JavaScript для загрузки содержимого, и в этом случае я бы рекомендовал вам либо обойти их API (посмотрите на HTTP-запросы, которые они посылают в браузере), или использовать селен , который способен исполнять код JavaScript (путем подключения его на ваш любимый веб-браузер) до анализа полученного HTML-теги.
