How to scrape google maps using python

Question

I am trying to scrape the number of reviews of a place from google maps using python. For example the restaurant Pike's Landing (see google maps URL below) has 162 reviews. I want to pull this number in python.

URL: https://www.google.com/maps?cid=15423079754231040967

I am not vert well versed with HTML, but from some basic examples on the internet I wrote the following code, but what I get is a black variable after running this code. If you could let me know what am I dong wrong in this that would be much appreciated.

from urllib.request import urlopen
from bs4 import BeautifulSoup

quote_page ='https://www.google.com/maps?cid=15423079754231040967'
page = urlopen(quote_page)
soup = BeautifulSoup(page, 'html.parser')
price_box = soup.find_all('button',attrs={'class':'widget-pane-link'})
print(price_box.text)

Solution

It's hard to do it in pure Python and without an API, here's what I ended with (note that I added &hl=en at the end of the url, to get English results and not in my language):

import re
import requests
from ast import literal_eval

urls = [
'https://www.google.com/maps?cid=15423079754231040967&hl=en',
'https://www.google.com/maps?cid=16168151796978303235&hl=en']

for url in urls:
    for g in re.findall(r'\[\\"http.*?\d+ reviews?.*?]', requests.get(url).text):
        data = literal_eval(g.replace('null', 'None').replace('\\"', '"'))
        print(bytes(data[0], 'utf-8').decode('unicode_escape'))
        print(data[1])

Prints:
