Python Object-Oriented Python Advanced Objects Double

Change the return statement to return the integer times 2. For example, Double(5) would return a 10.

Please help me with this

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

Hi, Thomas!

In step one, your new class should take 'int' as a parent. You're missing 'int' in your code above.

class Double(int):

In step 2, it's asking you to pass in self and one other argument, let's call it num. Then you need to use int to convert it and return that value:

class Double(int):
    def __new__(self, num):
        return int(num)

Then in step 3, you need to modify the return so it now returns the newly converted int times 2:

class Double(int):
    def __new__(self, num):
        return int(num) * 2

The goal here is to use int() as a function call. Right now, you are calling int's __new__ method and passing in values.

Thank you. This makes much more sense than the other ones i looked at. I actually understand whats going on here.
