# Hands Challenge 2/3 i don't understand the following error message

I'm getting this message when i check the code

Bummer: Didn't get `True` for `.doubles` on a pair

I try in different ways but i don't get where's my error :/

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 doubles(self):
for i in self:
if i == self:
return True
else:
return False

@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)
}
```

Your problem is your comparison. You write `for i in self`, thus each `i` must be an element in `self`, yet on the next line you test if `i` is equal to `self`. An element of a list can never be equal to the list itself.
