Continuing with the style and idioms issues...

1. Don't leave a space between a function/method/class name and the 
opening parenthesis, i.e. instead of:
	def execute (self):
use:
	def execute(self):

2. It seems to me that you indent your code with 2 spaces. If I'm wrong, 
please ignore me. Otherwise: always use 4 spaces when indenting with spaces.

Following these and the numerous other guidelines (see 
htpp://www.python.org/dev/peps/pep-0008/ for example) on Python style 
you'll be making yourself and others a favor. When these coding 
guidelines become your habit, it will be easier for you to read the code 
of other Pythoners. This is important because a large part of learning 
consists of reading the code of others.

And also vice versa: when you show your code to others, it will be 
easier for them to concentrate on your problem when the idiosyncrasy of 
your code is not there to hinder.

Cheers,
Jussi
