title: python dictionary with two values for each key or class?
body: <p>I need a data structure of this form:</p>
  
  <pre><code>   test_id1: resultValue, timeChecked
     test_id2: resultValue, timeChecked
     test_id3: resultValue, timeChecked
     test_id4: resultValue, timeChecked
     ...
  </code></pre>
  
  <p>up until now I have dealt with it by just using a dictionary with key value for the id and the result. But I would like to add the time I checked.
  What would be the best way to do this? Can I make the value a tuple? Or is a new class better suited in this case? 
  What would my class need to look like to accommodate the above?</p>
