Empty list while scraping Google Search Result

I'm trying to scrape Google Search Result but all I'm getting as an output is empty list. Do you have any idea what's wrong here? I found the similar post on Stack Overflow where solution says you should try putting user_agent. I tried but it still returns nothing. Please share if you have any idea.

import requests, webbrowser
from bs4 import BeautifulSoup

user_input = input("Enter something to search:")
print("googling.....")

google_search = requests.get("https://www.google.com/search?q="+user_input)
# print(google_search.text)

soup = BeautifulSoup(google_search.text , 'html.parser')
# print(soup.prettify())

search_results = soup.select('.r a')
# print(search_results)

for link in search_results[:5]:
    actual_link = link.get('href')
    print(actual_link)
    webbrowser.open('https://google.com/'+actual_link)

Solution

To get results from Google page, you have to specify User-Agent http header. For english results, add hl=en parameter to search URL:

import requests
from bs4 import BeautifulSoup


headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:77.0) Gecko/20100101 Firefox/77.0'}

user_input = input("Enter something to search: ")
print("googling.....")

google_search = requests.get("https://www.google.com/search?hl=en&q="+user_input, headers=headers)  # <-- add headers and hl=en parameter

soup = BeautifulSoup(google_search.text , 'html.parser')

search_results = soup.select('.r a')

for link in search_results:
    actual_link = link.get('href')
    print(actual_link)

Prints:

Enter something to search: tree

EDIT: To filter results you can use this:

import requests
from bs4 import BeautifulSoup


headers = {'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:77.0) Gecko/20100101 Firefox/77.0'}

user_input = input("Enter something to search: ")
print("googling.....")

google_search = requests.get("https://www.google.com/search?hl=en&q="+user_input, headers=headers)  # <-- add headers and hl=en parameter

soup = BeautifulSoup(google_search.text , 'html.parser')

search_results = soup.select('.r a')

for link in search_results:
    actual_link = link.get('href')
    if actual_link.startswith('#') or \
       actual_link.startswith('https://webcache.googleusercontent.com') or \
       actual_link.startswith('/search?'):
        continue
    print(actual_link)

Prints (for example):

Enter something to search: tree
