Stuck on what to do!!

And, finally, double (multiply by two) the int that you created in new. Return the new, doubled value. For example, Double(5) would return a 10.

doubler.py 
class Double(int):
    pass

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

Why are you able to pass with arg and not with args when all I see Kenneth use is args and kwargs

Alex Davis whatever follows the asteric doesnt really matter. It could even be var or vars. You can read more about *args and **kwargs in the following link; https://pythontips.com/2013/08/04/args-and-kwargs-in-python-explained/

I think the question was just confusing or at least it could of been worded much different for only adding 2 * after return.

class Double(int):
    def __new__(value,keyword):
        self = int.__new__(value,keyword)
        self *=   2
        return self

print(Double(5))
