beautifulsoup grabs the class keyword

Here we want to filter by class, but class is the keyword of python , what should we do? Just add an underscore

soup.find_all("a", class_="sister") # [<a class="sister" href="http://example.com/elsie" id="link1">Elsie</a>, # <a class="sister" href="http://example.com/lacie" id="link2">Lacie</a>, # <a class="sister" href="http://example.com/tillie" id="link3">Tillie</a>]

soup . find_all ( "a" , class_ = "sister" ) # [<a class="sister" href="http://example.com/elsie" id="link1">Elsie</a>, #  <a class="sister" href="http://example.com/lacie" id="link2">Lacie</a>, #  <a class="sister" href="http://example.com/tillie" id="link3">Tillie</a>]
