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).
