Python 3: Problem with Tkinter Tutorial

Problem:
I was searching GUI toolkit for Python 3.1.3, and I came across this hello world example (for Python 2) which utilize Tkinter. The code looks simple enough, so I gave it a try but got the following error:

Traceback (most recent call last):   File "C:\hello_world.py", line 1, in module     from Tkinter import * ImportError: No module named Tkinter

Solution:
Simply change the module name to "tkinter" (lower case) instead.
