title: Python Top trumps
body: <p>Any help would be appreciated
  I have a dictionary containing cards names and their corresponding statistics, for example:</p>
  
  <pre><code>{'Bob': [1, 3, 6, 5], 'Dave': [1, 8, 5, 5], 'Steve': [1, 3, 9, 7], 'John': [6, 7, 9, 5], 'Bill': [7, 3, 9, 1], 'Rodger': [4, 5, 2, 8]}
  player = dict()
  computer = dict()
  </code></pre>
  
  <p>But I am unsure on how to randomly assign cards into two different variables, such that both variables contain the same number of cards, each card is used once and none of the cards are in both variables.
  Anyone know how to help?</p>
