import requests from bs4 import BeautifulSoup base_site="https://en.wikipedia.org/wiki/Music" response=requests.get(base_site) html=response.content soup=BeautifulSoup(html,"html.parser") a=soup.find_all("a",class_="mw-jump-link") a['class']

Just for surety did you check a by printing it, may be soup didn't find the class you are going through so a just has an empty list so a['class'] might throws an error Hope this would be helpful to you Mayank
