title: Check if argument (tuple) is in dictionary
body: <p>I'm really struggling on unpacking and iterating over the tuples in this dictionary.  Essentially, the function takes a two coordinate position (Wx, Wy) and checks to see if it is in one of the tuples located in either list, in the dictionary, bonuses.  I feel like I'm overthinking it, or am just way off.</p>
  
  <p>Thanks :)</p>
  
  <pre><code>bonuses = {1: [(3,3)], 2: [(1, 0), (0, 3), (2, 4), (5, 2)]}
  
  def find_bonus(pos):
  """ Check if position is valid"""
  
      bonus_info = dict.values(bonuses)
  
      for (Wx, Wy) in pos:
          if (Wx, Wy) in tuple(bonus_info):
              return pos
      else:
      return False
  </code></pre>
