title: How to separate a tuple into two independant lists?
body: <p>I would like to separate the following tuple into two lists</p>
  
  <pre><code>(('happy', 5.001), ('neutral', 10.004), ('neutral', 15.006), ('happy', 20.071), 
   ('fear', 25.071))
  </code></pre>
  
  <p>I want my lists to look like the following:</p>
  
  <pre><code>a = ('happy', 'neutral', 'neutral', 'happy', 'fear')
  b = (5.001, 10.004, 15.006, 20.071, 25.071)
  </code></pre>
  
  <p>The <code>split()</code> method is not working on this. </p>
