title: Accessing an attribute using a variable in Python
body: <p>How do I reference <code>this_prize.left</code> or <code>this_prize.right</code> using a variable?</p>
  
  <pre><code>from collections import namedtuple
  import random 
  
  Prize = namedtuple("Prize", ["left", "right"]) 
  this_prize = Prize("FirstPrize", "SecondPrize")
  
  if random.random() &gt; .5:
      choice = "left"
  else:
      choice = "right"
  
  # retrieve the value of "left" or "right" depending on the choice
  print("You won", this_prize.choice)
  
  AttributeError: 'Prize' object has no attribute 'choice'
  </code></pre>
