title: dimensions of a +--+ box in Python 3.4
body: <p>This is my problem</p>
  
  <p>Create a program that accepts a number inputted by the user. This number defines the dimensions of a square and can be any positive integer.  An input of 1 will output:</p>
  
  <pre><code>    +--+
      +--+
  
  while an input of 2 will output
  
      +--+--+
      +--+--+
      +--+--+
  
  and an input of 3 will output
  
      +--+--+--+
      +--+--+--+
      +--+--+--+
      +--+--+--+
  
  etc…Show outputs for user inputs of 1, 2, 3, and 4. 
  </code></pre>
  
  <p>Not entirely sure where to start on this one and would like some advice, however i'm not looking for a complete answer (after all, this is homework) but something to point me in the right direction would be very much appreciated.</p>
