title: Python turtle.pensize() not changing the size of the pen
body: <p>I am trying to change the pen size in Python 2.7. I know the <code>pensize()</code> command can be interchanged with <code>width()</code> (neither work), however the size of the pen stays the same no matter what value I enter. We use WingIDE to program in Python, though using the Python IDE doesn't fix the issue.</p>
  <p>I have tested this on 3 machines, same issue. I have played with the positioning of the <code>turtle.pensize()</code>, size remains the same. The code below will draw the letter &quot;I&quot; and begin on a second letter:</p>
  <pre><code>import turtle
  
  t = turtle.Pen()
  turtle.bgcolor(&quot;black&quot;)
  turtle.pensize(800)
  
  t.reset()
  t.color(&quot;green&quot;);
  
  t.pu();
  t.setx(-450);
  t.pd();
  
  t.left(90);
  
  t.forward(120);
  
  t.pu();
  t.right(90);
  t.forward(90);
  t.right(90);
  t.pd();
  
  #I
  
  t.forward(120);
  t.left(90);
  t.forward(20);
  
  reset()
     
  </code></pre>
  <p>I don't really receive an error, but I will post what the WingIDE debugger displays:</p>
