title: Possible to have same key pair more than once in a dictonary
body: <p>I'm creating a blackjack game with a deck of cards like so:<br>
  <code>cards = {'ace':[1,11],'2':2,'3':3}...</code> and so on.  </p>
  
  <p>I want to have <code>3</code> decks of cards, so is it possible to have more than one ace, etc.? If so, how? I still want each card to have the keypair of its value, but I don't care if it's in a dictionary. </p>
