How to scrape 'People also ask' box from Google search?

I need to scrape the "People also ask box" from Google for questions and answers.

I make a search on google, then scrape it with BeautifulSoup.

import requests
from bs4 import BeautifulSoup
import html2text
import urllib.request

link = "https://www.google.com/search?client=firefox-b-d&source=hp&ei=v0mUXPu2ApTljwS6iLnABA&ei=lAyVXMPFCsaUsgXqmZT4DQ&q=what+is+java"

headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36'}
page = requests.get(link ,headers = headers)
soup = BeautifulSoup(page.content, 'html.parser')
#For answers :
mydivs = soup.find_all('div', class_="ILfuVd NA6bn")

The results are an empty list. I checked in the html file and the answers are in fact under that class. What is wrong with my code?

Google's frontpage updates when you enter text in the search box, so you won't be able to get the results while making a simple request to the search page.

You can go to https://google.com in your browser, open the Development Tools panel (usually F12) and watch the Network tab to see the underlying requests being made to the autocomplete API.

It looks like the endpoint is https://www.google.com/complete/search?q=yourQueryHere&client=psy-ab, which is easier to query than an HTML page:

query = "what is java"
res = requests.get("https://google.com/complete/search?client=psy-ab&q=" + query)
print(res)

Also, Google probably doesn't want people to scrape this so you will probably hit rate-limiting if you do too many requests.

  1. To get answers you can use selenium click methods or other libraries that can simulate clicks.
  2. Extract directly from Javascript:enter image description here
  3. Using Google Related Questions API from SerpApi. It's a paid API with a free trial. Check playground.

Code and example:

from serpapi import GoogleSearch
import os

params = {
  "engine": "google",
  "q": "what is java",
  "api_key": os.getenv("API_KEY"),
}

search = GoogleSearch(params)
results = search.get_dict()

for q_and_a in results['related_questions']:
  print(f"Question: {q_and_a['question']}\nAnswer: {q_and_a['snippet']}\n")

Output:
