title: How do I get random values from nested dictionaries?
body: <p>So, I'm fairly new to Python and trying to teach myself with the help of some books right now. I'm currently working on a personal project where I simulate a hand of playing cards. I have a dictionary with four nested dictionaries representing each suit, and for each of those dictionaries I have all cards that would be present.</p>
  
  <p>I've tried searching for ways to get these values, but everything I've found has either been for Python 2.x and doesn't work anymore, or only seems to go one dictionary deep.</p>
  
  <pre class="lang-py prettyprint-override"><code>deck = {
      'Spades': {'Aces': 1, 'Twos': 1, 'Threes': 1, 'Fours': 1, 'Fives': 1, 'Sixes': 1, 'Sevens': 1, 'Eights': 1, 'Nines': 1, 'Tens': 1, 'Jacks': 1, 'Queens': 1, 'Kings': 1},
      'Diamonds': {'Aces': 1, 'Twos': 1, 'Threes': 1, 'Fours': 1, 'Fives': 1, 'Sixes': 1, 'Sevens': 1, 'Eights': 1, 'Nines': 1, 'Tens': 1, 'Jacks': 1, 'Queens': 1, 'Kings': 1},
      'Hearts': {'Aces': 1, 'Twos': 1, 'Threes': 1, 'Fours': 1, 'Fives': 1, 'Sixes': 1, 'Sevens': 1, 'Eights': 1, 'Nines': 1, 'Tens': 1, 'Jacks': 1, 'Queens': 1, 'Kings': 1},
      'Clubs': {'Aces': 1, 'Twos': 1, 'Threes': 1, 'Fours': 1, 'Fives': 1, 'Sixes': 1, 'Sevens': 1, 'Eights': 1, 'Nines': 1, 'Tens': 1, 'Jacks': 1, 'Queens': 1, 'Kings': 1}
  }
  </code></pre>
  
  <p>I want to create a function that will return a random card, and I can get one random value from the deck variable, using <code>random.choice(list(deck.keys()))</code>, but I can't get into those dictionaries, and I feel that it's really simple and I'm just being dumb.</p>
