I know this is way off but I'm not sure how to get this to multiply.
class Double(int):
def __new__(cls, *args, **kwargs):
self = super().__new__(cls, *args, **kwargs)
def __mul__(self, other):
if int = 5
if other = (int) *2
return (int)* other

In the early tasks, the __new__ method is missing a return statement. Something like return self works.
Now the cool part! For Task 3, you really only need to add “* 2” to the __new__ return statement.
This works because the self * 2 calls the __mul__ method inherited from int. However, since you created your own __mul__ method, it overrides the inherited version. Therefore your local method has to work to pass Task 3.
def __mul__(self, other):
return int(self) * other
would get it done ✅. Or, simply delete the whole __mul__ method.
Post back if you need more help. Good luck!!!
