title: Good way of handling NoneType objects when printing in Python
body: <p>How do I go about printin a NoneType object in Python?</p>
  
  <pre><code># score can be a NonType object
  logging.info("NEW_SCORE : "+score)
  </code></pre>
  
  <p>Also why is that sometime I see a comma instead of the + above?</p>
