title: Python : Extract values from List of tuples
body: <p>There are other questions posted for the topic but I have different issue. 
  I have a list of tuples which I made by finding maximum three scores and corresponding values from two list:</p>
  
  <pre><code>score = [0.133961, 0.026456, 0.210888, 0.521684, 0.156776]
  tone = [u'Anger', u'Disgust', u'Fear', u'Joy', u'Sadness'] 
  </code></pre>
  
  <p>and used</p>
  
  <pre><code>highest_three = sorted(zip(score, tone_name), reverse = True)[:3]
  </code></pre>
  
  <p>to get the output :</p>
  
  <p>[(0.521684, u'Joy'), (0.210888, u'Fear'), (0.156776, u'Sadness')]</p>
  
  <p>Now I only want to print in output.</p>
  
  <pre><code>Joy, Fear, Sadness
  </code></pre>
  
  <p>I used :</p>
  
  <pre><code>emo = ', '.join ('{}'.format(*el) for el in highest_three)
  </code></pre>
  
  <p>but this returns the score and I want to print tone_name only. Any suggestions ?</p>
