Joining fields values

Question

I have classes structure like this:

class A(object):
    array = [1]

    def __init__(self):
        pass

class B(A):
    array = [2, 3]

    def __init__(self):
        super(B, self).__init__()

class C(B):
    array = [4]

    def __init__(self):
        super(C, self).__init__()
        print array

And when I do:

c = C()

I want it to join all their fields in the order of inheritance. And print [1, 2, 3, 4]. How can I do that?

Answer 1

Well when you define array in each class, it's going to override the value of the inherited class.

If you want to do this, then change your class definitions, and add the array initialisation into the __init__(self) function of each class.

I.e.

class A(object):
    array = [1]
    def __init__(self):
        pass

class B(A):
    def __init__(self):
        super(B, self).__init__()
        self.array += [2,3]

class C(B):
    def __init__(self):
        super(C, self).__init__()
        self.array += [4]
        print self.array
