object.__init__() takes no parameters

Question

import abc

class AbsBaseClass(abc.ABC):
    def __init__(self,x):
        self.x=x

class DerivedClass(AbsBaseClass):
    def __init__(self,y):
        super(AbsBaseClass,self).__init__(y)


ob=DerivedClass(5)

Answer 1

The error is here:

class DerivedClass(AbsBaseClass):
    def __init__(self,y):
        super(AbsBaseClass,self).__init__(y)
 #            ^^^^^^^^^^^^ This should be DerivedClass, not AbsBaseClasee

Answer 2

Additional, to @NPE's answer.

• you're doing a class as super which is the metaclass, so then if you want that, why not have an empty super ?

• That's all really :-)...

So code becomes:

import abc

class AbsBaseClass(abc.ABC):
    def __init__(self,x):
        self.x=x

class DerivedClass(AbsBaseClass):
    def __init__(self,y):
        super(DerivedClass,self).__init__(y) #!!!


ob=DerivedClass(5)

So instead of:

super(AbsBaseClass,self).__init__(y)

Do:

super(DerivedClass,self).__init__(y)
