I am getting:
Couldn't find a tree builder with the features you requested: parser.html. Do you need to install a parser library?
when ever I try to parse my page. Please for help for I am still not very good at python.
import requests
from bs4 import BeautifulSoup
response = requests.get("http://stackoverflow.com/questions")
soup = BeautifulSoup(response.text,"parser.html")
questions = soup.select(".question-summary")
