title: Can I set a variable to nothing?
body: <p>The question kind of explains it. I was thinking it would be something like:</p>
  
  <pre><code>x = None
  if sUserInt == x:
      #do stuff here
  </code></pre>
  
  <p>I'm using it to check if a user has just pushed enter and put nothing in at all.
  Thanks!</p>
