title: Can't instantiate abstract class IEXStockFetcher with abstract methods fetchImageURL, fetchPrice, fetchStockHighLow
body: <p>I am trying to get this awesome code I found on Github to compile <a href="https://github.com/apryor6/stockstreamer/blob/master/data_fetcher.py" rel="nofollow noreferrer">https://github.com/apryor6/stockstreamer/blob/master/data_fetcher.py</a></p>
  
  <p>I made a few modifications to the code as API URL for IEX has changed this code was published</p>
  
  <pre><code>Class IEXStockFetcher(StockFetcher):
  
      """
      Fetches stock information using iextrading.com API
      """
      url_prefix = "https://cloud.iexapis.com/stable/stock/market/batch?token=MY TOKEN"
  
      url_suffix_price = "&amp;price"
      url_suffix_img = "&amp;logo"
      url_suffix_highlow = "&amp;quote"***
  
  
  When I step through the code and get to the end I receive the following error: "Can't instantiate abstract class IEXStockFetcher with abstract methods fetchImageURL, fetchPrice, fetchStockHighLow"
  
  I am relatively new to object oriented programing in Python. Anyone has any thoughts?
