title: How to catch empty user input using a try and except in python?
body: <p>I am trying to figure out how I can catch empty user input using a try and except.
  If you had this for example:</p>
  
  <pre><code>try:
      #user input here. integer input 
  except ValueError:
      #print statement saying empty string.
  </code></pre>
  
  <p>Although I also need to catch another value error to make sure they entered an integer and not a character or string how could I use an if and elif setup in order to figure out if it is an empty string or str instead of int  </p>
