从网站上抓取文字值，但出现AttributeError

Question

我正在尝试从Bloomberg网站上抓取文本值“ S＆P 500 Index”，但收到错误：

  

回溯（最近通话最近）：     在第17行的文件“ tester.py”中       名称= name_box.text.strip（）   AttributeError：'NoneType'对象没有属性'text'

我的Python代码：

# -*- coding: utf-8 -*-
#import libraries
import requests
from bs4 import BeautifulSoup
import requests
from requests.packages.urllib3.exceptions import InsecureRequestWarning
requests.packages.urllib3.disable_warnings(InsecureRequestWarning)

#query the website and return the html to the variable ‘page’
page = requests.get('https://www.bloomberg.com/quote/SPX:IND', verify=False)

#parse the html using beautiful soup and store in variable `soup`
soup = BeautifulSoup(page.content,'html.parser')

#get the companyName
name_box = soup.find('h1', attrs={'class': 'companyName__99a4824b'})
name = name_box.text.strip()
print(name_box)

#get the index price
price_box = soup.find('div', attrs={'class':'price__c3a38e1d'})
price = price_box.text
print(price)
