title: Using pass on a non necessary else statement
body: <p>Based on PEP8 documentation, I was not able to find any reference regarding if I should use <code>pass</code> for aesthetic reasons on code. Based on the example below, should I keep those <code>else</code> or can I erase them?  Until now, the main reason I'm keeping it is based on the mantra "Explicit is better than implicit."</p>
  
  <pre><code>if fields:
      for i in foo:
          if i == 'something':
              print "something"
          else:
              pass
  else:
      pass
  </code></pre>
