title: python turtle on mac not working
body: <p>I am trying to use a python import of turtle but i get an error:</p>
  
  <pre><code>Traceback (most recent call last):
    File "turtle.py", line 1, in &lt;module&gt;
      import turtle
    File "/turtle.py", line 32, in &lt;module&gt;
      turtle.pensize(2)
  AttributeError: 'module' object has no attribute 'pensize'
  </code></pre>
  
  <p>Does the python come with turtle or i have to download it separately?</p>
  
  <p>My python is 2.7.2</p>
