title: Necessity of an 'empty' else statement in Python
body: <p>I have now seen the following multiple times in some python tutorials.</p>
  
  <pre><code>if True:
      do something
  else:
      pass
  </code></pre>
  
  <p>To me the else statement seems pretty unnecessary. Is this just to make the code more clear? Or is there some safety reason why this needs to be done? Thanks.</p>
