I know I am dong something wrong. can someone help me?

I am at the last task of the objects course, and I have a question like this:

And, finally, if I have doubles, I want to reroll the hand. Add a classmethod to CapitalismHand named reroll that returns a new instance of the class, effectively rerolling the hand.

I have rewatched the video various times but I couldn't figure it out.

My code for that challenge is at the bottom of the question.

Can someone tell me how to fix this?

Thanks!

hands.py
```from dice import D6

class Hand(list):
def __init__(self, size=2, die_class=D6, *args, **kwargs):
if not die_class:
raise ValueError("You must provide a die class")
super().__init__()

for _ in range(size):
self.append(die_class())
self.sort()

def _by_value(self, value):
dice = []
for die in self:
if die == value:
dice.append(die)
return dice

class CapitalismHand(Hand):
@property
def ones(self):
return self._by_value(1)

@property
def twos(self):
return self._by_value(2)

@property
def threes(self):
return self._by_value(3)

@property
def fours(self):
return self._by_value(4)

@property
def fives(self):
return self._by_value(5)

@property
def sixes(self):
return self._by_value(6)

@property
def _sets(self):
return {
1: len(self.ones),
2: len(self.twos),
3: len(self.threes),
4: len(self.fours),
5: len(self.fives),
6: len(self.sixes)
}
@property
def doubles(self):
if self[0] == self[1]:
return True
return False

@classmethod
def reroll(cls):
if self.doubles == True:
return cls(Hand().__init__())
```

Hey, good effort! Remember self is not an argument of a @classmethod so therefore you cant use it. Instead you can use the cls argument. You only need to return the class again to roll again. Also as a little tip, to check if something is true you can just do - if self.doubles:

```@classmethod
def reroll(cls):
if cls.doubles:
return cls()
```
