title: Why is this printing 'None' in the output?
body: <p>I have defined a function as follows:</p>
  
  <pre><code>def lyrics():
      print "The very first line"
  print lyrics()
  </code></pre>
  
  <p>However why does the output return <code>None</code>: </p>
  
  <pre><code>The very first line
  None
  </code></pre>
