title: Python: Tkinter & turtle
body: <p>Beginning programmer here. From How to Think Like a Computer scientist I got the following code:</p>
  
  <pre><code>#!/usr/bin/env python3
  
  import turtle
  wn = turtle.Screen()
  alex = turtle.Screen()
  alex.forward(150)
  alex.left(90)
  alex.forward(150)
  </code></pre>
  
  <p>The program seems simple enough, Yet I get the following error:</p>
  
  <pre><code>ImportError: No module named turtle
  </code></pre>
  
  <p>After some internet research, I read that the turtle module can me found within the tkinter package. And so because I have two different python installations, Python 2.7.3 and Python 3.2.3</p>
  
  <p>I ran the following commands in Ubuntu terminal, in hopes to install the missing python modules:</p>
  
  <pre><code>sudo apt-get install python-tk
  sudo apt-get install python3.2-tk
  </code></pre>
  
  <p>It got me nowhere. 
  So how can I install the missing modules for both versions of python? </p>
  
  <p>Thanks!</p>
