I think you mean the following:
You'd like to do
p = Person('me', 'here', 31)
and you are wondering why you need the __init__() function in
class Person(object):
def __init__(self, name, addres, age):
self.name = name
self.address = address
self.age = age
right?
If so, the answer is that while you think you are doing "Person('me', 'here',
31)",
you are in reality executing "Person.__init__(self, 'me', 'here', 31)", where
'self' is refers to a shiny new, empty object created for you.
(and the 'self' is obtained by the Person.__new__ function I think, but others
here have much better knowledge about this).
Sincerely,
Albert
