I'm learning python and oo at the same time. I'm currently looking for more
grounding in practical ooa and ood. The basic question is "How do I know
what to make objects out of and what are the pitfalls of doing it this way
vs. that way?"
I have read various chunks here and there, saying things like, "Inheritance is
not good because it creates dependencies", or "Aggregation is good but it's a
pain to implement the proxy methods". Then we have the Extreme camp which
says, "Sstart with a few objects and reiteratively ooa and ood as you go
along". I realize that some of this is being distilled as patterns (and I
like what little I've seen of the Extreme camp). That's great if you know
what they are and where to apply them.
I tend to be a very-big-picture thinker. I like to have a framework to hang
things on rather than starting at it piecemiel. Is there a solid set of
general principles for ooa and ood that I can begin to build upon?
Are there any textbooks out there that start with oo (even ooa and ood) and
build from there? I see that introductory books deal with the language
elements and a basically procedural orientation, then add oo later as
"advanced". I'd love to see a textbook that starts on oo and builds on it.
I'm fairly sure that no such book exists for Python but I'd love to be proven
wrong!
Cordially,
Scott
