[BangPypers] how to delete base class attribute

[Mehndi, Sibtey]

Nitin,
         del can only remove the elements present in the instance dictionary. If you check self.__dict__ then it shows that A is not in the dictionary only 'a' and 'b' exist in the dict that's why it is giving the attribute error.

Subject: [BangPypers] how to delete base class attribute

Hi all,



Say I have 10 functions in base class and I have inherited it in some
derived class.

But I only want 9 of the base class function to be available in child class.
(and I don't want to make that one class private)



class x:

    def __init__(self):

        self.a =3

        self.b= 4

    def A(self):

        print (self.a)

    def B(self):

        print (self.b)



class y(x):

    def __init__(self):

        x.__init__(self)

        del (self.A)                                  #This is giving    del
(self.A)

AttributeError: A
