Understanding Python super() with __init__() methods

Question

I am a learner and just want to know the basic concept of super().

Here in the given code I want to know the difference between the two child classes:

    class Base(object):

    def __init__(self):

    print "Base created"

    class ChildOne(Base):

    def __init__(self):

    Base.__init__(self)

    class ChildTwo(Base):

    def __init__(self):

    super(ChildTwo, self).__init__()

    ChildOne()

    ChildTwo()

Answer 1

@Shubham, You can avoid referring to base class explicitly using super(). Multiple-inheritance is not possible without using super().

Python also changed its syntax in version 3.0 , super()._init_() and super(ChildTwo, self)._init_() both perform the same function but the later is a bit nicer.

Answer 2

In Python 3, we can call it like this:

class ChildB(Base):

    def __init__(self):

        super().__init__()
