Hi Sandeep, If I am reading the same challenge as you, they want you to accept arguments and keywords. That would mean you want

def __new__(*args, *kwargs):
#and then go from there

As Frank mentioned, the parameters need to be *args, **kwargs. Calling the __new__ method returns an object. That object should be returned:

class Double(int):
    def __new__(*args, **kwargs):
        bob = super().__new__(*args, **kwargs)
        return bob

However, using super does not seem to work in this challenge (I've messaged Kenneth Love about it). Use the class name directly:

class Double(int):
    def __new__(*args, **kwargs):
        bob = int().__new__(*args, **kwargs)
        return bob

And you don't have to use "bob" :-)
