title: Web scraping from Google Finance: returned data list always empty
body: <p>I would like to scrape data (e.g., market capitalization, PE-ratio, etc.) from Google Finance using the BeautifulSoup-library of Python. However, when I try to extract certain passages (like "div", "tr", "td") from the html-code    of the corresponding Google Finance site, using the "find_all" function, I always receive an empty list (i.e., the "base" object in the code below is empty). </p>
  
  <p>During debugging, I printed the "soup" object and compared its content with the corresponding html-code. What surprised me was that the content of the "soup" object differs from the content of the html-code. I would expect that both should match in order to extract data successfully.</p>
  
  <pre><code>from bs4 import BeautifulSoup
  import urllib.request
  
  opener = urllib.request.build_opener()
  opener.addheaders = [('User-Agent', 'Mozilla/5.0')]
  response = opener.open('https://www.google.com/search?q=NASDAQ:GOOGL')
  
  soup = BeautifulSoup(response, 'html.parser')
  base = soup.find_all('div',{'class':'ZSM8k'})
  
  print(soup)
  print(base)
  </code></pre>
