title: python 2.7 - no module named tkinter
body: <p>i am on mac os x 10.8, using the integrated python 2.7.
  i try to learn about tkinter with tutorials like <a href="http://www.youtube.com/watch?v=uh6AdDX7K7U" rel="noreferrer">this</a> for python 2.7 (explicitly not 3)
  they propose the following code:</p>
  
  <pre><code>from tkinter import *
  import tkinter.messagebox
  </code></pre>
  
  <p>however, this brings up the error:</p>
  
  <pre><code>ImportError: No module named tkinter
  </code></pre>
  
  <p>using import.Tkinter with a capital t seems to work, but further commands like</p>
  
  <pre><code>import Tkinter.messagebox
  </code></pre>
  
  <p>don't (neither does tkinter.messagebox).
  I've had this problem with lots of tutorials. what's the thing with the capital / non-capital "T", and how do i get my python to work like it does in the tutorials? Thanks in advance!</p>
