Yes there are two ways to filtr by class:

>>> soup = bs4.BeautifulSoup("""
... <span class="one">alpha</span>
... <span class="two">beta</span>""")

Use attrs:

>>> soup.find_all(attrs={"class": "one"})
[<span class="one">alpha</span>]

Append an underscore:

>>> soup.find_all(class_="two")
[<span class="two">beta</span>]
