  WORDS = ("book","house","universe")

          break
      elif guess == hint:
          print "Hint:: There is a(n)", hint_letter, "in the word\n"
  
      else:
          if guess != gen_word:
              print "I am sorry that's not the word, try again.\n"
  
  
  
      guess = raw_input("Your Guess:")
  
  
  raw_input() 
  </code></pre>
  
  <p>The problem is that at  </p>
  
  <pre><code>  elif guess == hint:
          print "Hint:: There is a(n)", hint_letter, "in the word\n"
  </code></pre>
  
  <p>i don't understand why it only gives the same letter as a hint, shouldn't it pick a random letter from the word, each time the loop runs? For example i type in help and it gives me a, next time i typed in help it would give me b.</p>
