OO re-factoring (was Pythonese/Efficiency/Generalese critique [onTutor])

[Lee Cullens]

In my original post I noted my recent exposure to Python and put up a
little utility to my iDisk asking for a Pythonese/Efficiency/
Generalese critique.

Javier, Kent and Liam were gracious enough to offer comments, which
were greatly appreciated. To follow through with the learning
exercise, I incorporated their comments (at least the ones there were
no conflicting opinions on :~) and put up the new version as:

I was thinking of extending the learning exercise by re-factoring it
as an OO approach, since it would contain a minimum altered method.
Being new to OOP also though, I'm confusing myself with how that
would be best accomplished. My thinking is that class/subclass
method instances would replace the recursive functions approach, but
have as yet not formed the coding in my mind.

I've read a lot on OOP, but seem to have a problem with the practical
use of such in this utility. I'm undoubtedly creating a mountain of
an ant hill in my mind, so any thoughts would be appreciated.

Thanks,
Lee C

I don't remember the original post, but methods and recursion are *not*
mutually exclusive (e.g., an Integer class with a factorial method, or a
binary tree class whose nodes are also binary trees).

Also, don't think that you have to make everything OO.
OO isn't necessarily better than non-OO. It's a means
to an end, not an end in itself.
