Python - 如何将一个对象引用到另一个对象

Question

我正在努力解决的更基本问题......

给出下面的基本代码... person对象如何获得"附加"它的地址.

class Person(object):
    def __init__(self, fn, ln):
        self.uid    = Id_Class.new_id("Person")
        self.f_name = fn
        self.l_name = ln

class Address(object):
    def __init__(self, st, sub):
        self.uid    = Id_Class.new_id("Address")
        self.street = st
        self.suburb = sub

s = Person('John', 'Doe')

hm = Address('Queen St.', 'Sydney')

Answer 1

尝试:

class Person(object):
    def __init__(self, fn, ln, address):
        self.uid    = Id_Class.new_id("Person")
        self.f_name = fn
        self.l_name = ln
        self.address = address

class Address(object):
    def __init__(self, st, sub):
        self.uid    = Id_Class.new_id("Address")
        self.street = st
        self.suburb = sub

hm = Address('Queen St.', 'Sydney')

s = Person('John', 'Doe', hm)
