以编程方式获取Google中的索引页数？

import requests
from bs4 import BeautifulSoup

def get_google_index_pages(query):
    url = f'https://www.google.com/search?q={query}'
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
    response = requests.get(url, headers=headers)

    soup = BeautifulSoup(response.text, 'html.parser')
    result_stats = soup.find('div', {'id': 'result-stats'})

    if result_stats:
        result_stats = result_stats.text
        pages = result_stats.split('-')[1].strip().replace(',', '')
        return int(pages)
    else:
        return None

query = 'Python'
pages = get_google_index_pages(query)

if pages:
    print(f'Google 中 "{query}" 的索引页数为：{pages}')
else:
    print(f'无法获取 "{query}" 的索引页数')
