Hello all, I've been trying to go over my OO Patterns book, and I decided to try to implement them in Python this time around. I figured this would help me learn the language better.
Well, I've gotten stuck with my first go at OO patterns with Python. I guess it goes without say that some of the stuff that are taken for granted in most of the books (ie. Interfaces, Abstract classes) don't really apply to Python per say, but the idea behind the patterns can be extracted out still. In the specific case of the Strategy pattern, I think the goal is to abstract out of the class an algorithm that can then be reused by some of the inherited classes. This way we don't repeat ourselves. Maybe I got this all wrong... I'm at a loss at how I can do this with Python, any pointers would be more than welcomed! To aid commenters... we can use the example used in "Head First Design Patterns". I've implemented this simple patter in Java and .NET... now in python. I can't draw UML here, so I'll try to pseudo talk what the example has: Abstract Base Class: Duck + FlyBehavior _fly + swim() + fly() -> calls _fly.fly() Interface: FlyBehavior + fly() Concrete Interface FlyHigh (implements FlyBehavior): + fly() Concrete Class Duck1 (Inherits Duck): + Constructor: _fly = new FlyHigh() Daniel. -- http://mail.python.org/mailman/listinfo/python-list
