在Python 3中获取Google搜索结果的数量

有没有办法在Python3中返回谷歌搜索结果的数量?我尝试了SO的几种方法,但没有一种仍然有效:

>>> import requests
>>> from bs4 import BeautifulSoup

>>> def get_results(name):
        re = requests.get('https://www.google.com/search', params={'q':name})
        soup = BeautifulSoup(re.text, 'lxml')
        response = soup.find('div', {'id': 'resultStats'})
        return int(response.text.replace(',', '').split()[1])

>>> get_results('Leonardo DiCaprio')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 5, in get_results
AttributeError: 'NoneType' object has no attribute 'text'
