title: Comparing List against Dict - return key if value matches list
body: <p>This is Python 3.6 </p>
  
  <p>I need help comparing a list against a dictionary and if there is match I need to return the dictionaries key.</p>
  
  <pre><code>champ_ids = [0, 36, 85]
  
  champ_dict = {Bob : 0, Carly: 36, Freddy : 85, Megan : 14, Dilbert : 69}
  
  for item in champ_dict.items() and champ_ids:
      print(item)
  </code></pre>
  
  <p>That prints all the matching numbers so in this case <code>0, 36, 85</code> which is perfect. How do I make it return <code>Bob, Carly, Freddy</code> (the keys) if those values are found in both places, instead of returning the values that match</p>
