title: How do you create a n by n box of X's in python using string manipulation? (eg. replace, count, find, len, etc.)
body: <p>Get a number from the user (n) and create an n x n box of "X"es on the screen. Without using loops yet.
  e.g. If they entered 12: </p>
  
  <pre><code>XXXXXXXXXXXX
  XXXXXXXXXXXX
  XXXXXXXXXXXX
  XXXXXXXXXXXX
  XXXXXXXXXXXX
  XXXXXXXXXXXX
  XXXXXXXXXXXX
  XXXXXXXXXXXX
  XXXXXXXXXXXX
  XXXXXXXXXXXX
  XXXXXXXXXXXX
  XXXXXXXXXXXX
  </code></pre>
  
  <p>The point of this assignment is to use string manipulation to create this box.  I can do it with a loop but I'm not sure how to do it with just strings.  Can anyone help me out?</p>
