Your answer is quite good. I am not a purist myself (when it comes to
Java and C++, I am never going to instantiate a Math class to get a
logarithm function), but I understand the value of OO from experience.
As I mentioned those "tuples and dictionaries" to pass data around, I
would like to add that when a single script has two kinds of tuples or
dictionaries, you may be better of using two different classes, as
having "dedicated" types simplifies project organization and
enhances readability.

I have never gone "seriously OO" with Python though. I never wrote
from scratch an application with more than 10 classes as far as I can
remember. However, I would suppose that the interpreter can handle
thousands of user-defined classes simultaneously.
