python - Unable to scrape google news heading via their class

I am trying to scrape google news headings along with their links for input term. But when I searched via find_all method for a class that contains all news headings, it returned an empty list.

I tried with parent divs with their id's but the result wasn't different.

import requests
from bs4 import BeautifulSoup

input_term = input("Enter a term to search:")
source = requests.get("https://www.google.com/search?q={0}&source=lnms&tbm=nws".format(input_term)).text
soup = BeautifulSoup(source, 'html.parser')

#here 'bkWMgd' is class that I found to be contained all search results.
heading_results = soup.find_all('div', class_ = 'bkWMgd')
print(heading_results)

I want to scrape all news headings and their respective links. I expected a list of all search result from the above code. But it returning an empty list.

The response that is seen by beautifulsoup and the one in your browser is quite different due to the presence of Javascript. Hence the selectors that you use might vary. It's always a good idea to print the response that you receive from beautifulsoup and analyze the HTML & then decide the selectors using class/id appropriately.

import requests
from bs4 import BeautifulSoup

input_term = input("Enter a term to search:")
source = requests.get(
    "https://www.google.com/search?q={0}&source=lnms&tbm=nws".format(input_term)).text
soup = BeautifulSoup(source, 'html.parser')

# here div#ires contains an ol which contains the results.
heading_results = soup.find("div", {"id": "ires"}).find("ol").find_all('h3', {'class': 'r'})
# Loop over each item to obtain the title and link (anchor tag text and link)
print(heading_results)
