Python has several popular packages that can parse HTML using CSS selectors.
The most popular one is BeautifulSoup which can execute CSS selectors through the select() and select_one() methods:
from bs4 import BeautifulSoup
soup = BeautifulSoup("""
<a>link 1</a>
<a>link 2</a>
""")
print(soup.select_one('a'))
"<a>link 1</a>"
print(soup.select('a'))
["<a>link 1</a>", "<a>link 2</a>"]
Another popular package is parsel (also used by scrapy) which can execute CSS selectors through the css() method:
from parsel import Selector
soup = Selector("""
<a>link 1</a>
<a>link 2</a>
""")
print(soup.css('a').get())
"<a>link 1</a>"
print(soup.css('a').getall())
["<a>link 1</a>", "<a>link 2</a>"]
