Python: Inherit the superclass __init__

Question

I have a base class with a lot of __init__ arguments:

class BaseClass(object):
    def __init__(self, a, b, c, d, e, f, ...):
        self._a=a+         


        

Answer 1

Perhaps a clearer implementation for your case is using **kwargs combined with new added arguments in your derived class as in:

class Parent:
    def __init__(self, a, b, c):
        self.a = a
        self.b = b
        self.c = c


class Child(Parent):
    def __init__(self, d, **kwargs):
        super(Child, self).__init__(**kwargs)
        self.d = d

By this method you avoid the code duplication but preserve the implicit addition of arguments in your derived class.
