title: Empty String Boolean Logic
body: <p>I just stumbled across this and I couldn't find a sufficient answer:</p>
  
  <pre><code>x = ""
  </code></pre>
  
  <p>Why then is:</p>
  
  <pre><code>x == True
  False
  
  x == False
  False
  
  x != True
  True
  
  x != False
  True
  </code></pre>
  
  <p>Am I supposed to conclude that <code>x</code> is neither <code>True</code> nor <code>False</code>?</p>
