Hussein, I don't think you'll learn much from asking these abstract questions. At some point you have to get your hands dirty and write actual code to get a feel for the language. For example, it will then become obvious for you that property works best for individual attributes while __getattr__ and friends are more convenient if you want to treat multiple attributes the same way, attributes whose names may not even be known until runtime (think delegation).
