title: How to get the maximum value from a dict and determine the key where the maximum is from?
body: <pre><code>sets={'Billy': [85, 76, 92], 'Sara': [55, 90, 68], 'Ben': [100, 80, 40]}
  </code></pre>
  
  <p>I'm trying to use sets.values() but I later figured out that I have to think another way since it will be the hard way to indicate who got the highest value.</p>
  
  <pre><code>for i in range(len(sets.values())):
      a= list(sets.values())[i][0]
      print(a)
  </code></pre>
  
  <p>The highest value has to be picked from the first value[0] from each list that Billy, Sara, Ben has. For example, the highest value of the second score is 90 which comes from 76, 90, 80 #sets[i][1].
   The output I want is:</p>
  
  <pre><code>[Ben, Sara, Billy]
  </code></pre>
  
  <p>Can you give me some tips, please?  </p>
