Parsing in python does not work, what should I do?

Question

Python

Hello. The task is to write a parser for this site . I wrote a script, but it does not give the result, but gives out the main page, please help.

import requests
from bs4 import BeautifulSoup

number = input('Введите номер: ') 
URL = 'https://phonebook.space/?input=%2B' + number 
HEADERS = {'user_agent':'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:86.0) Gecko/20100101 Firefox/86.0', 'accept': '*/*'}

def getHtml(url, params=None):
    r = requests.get(url, headers = HEADERS)
    return r

def parse():
    html = getHtml(URL)
    print(html.status_code)
    print(html.text)

parse()

Answer 1

Firstly, the user_agent header does not exist
. Secondly, why can't I parse information from the site?
