title: How to get stock rating on Robin_Stocks robin_stocks.stocks.get_ratings function
body: <p>Peeps, 
  I am using robin_stocks to get stock quotes Robinhood and interested in getting rating of stock using this function: robin_stocks.stocks.get_ratings as follow:</p>
  
  <pre><code>quotes = robin_stocks.stocks.get_ratings('AAPL', )
  print(quotes)
  </code></pre>
  
  <p>I get a very long string as follow (cut it short to save space here) :</p>
  
  <pre><code>{'summary': {'num_buy_ratings': 26, 'num_hold_ratings': 13, 'num_sell_ratings': 3 .... 
  </code></pre>
  
  <p>How can I modify my code to get just the numbers i.e. 26, 13, and 3 so that I can run my calculations.</p>
  
  <p>if I use: </p>
  
  <pre><code>quotes = robin_stocks.stocks.get_ratings('AAPL', 'num_buy_ratings')
  </code></pre>
  
  <p>I get error as follow: </p>
  
  <pre><code>Error: The keyword "num_buy_ratings" is not a key in the dictionary.
  </code></pre>
  
  <p>I am not advance in python, if you can help, I very much appreciate it.
  Thanks,</p>
