title: Fixing code to make a triangle
body: <p>I'm a beginner and trying to learn Python by myself. I've been working on coding some basic shape exercises, so far I have the following code to make a diagonal.</p>
  
  <pre><code>size = input('Please enter the size: ')
  chr  = raw_input('Please enter the drawing character: ')
  
  row = 1
  while row &lt;= size:
  
      col = 1
      while col &lt; row:
          print ' ', 
          col = col + 1
      print chr
  
      row = row + 1
  print ''
  </code></pre>
  
  <p>I get this output :</p>
  
  <pre><code>X
   X
    X
     X
  </code></pre>
  
  <p>I would love some help on how to make this into a triangle like this....</p>
  
  <pre><code>X X X X
    X X X
      X X
        X
  </code></pre>
  
  <p>Any explanations on how to make the loop necessary for the characters to show up to make the triangle shaped output would be appreciated. </p>
