if there is a yatzy (5 dices with the same number), then length of one of these lists would be 5. What am I missing here?

```
def score_yatzy(self, hand):
if 5 in {len(hand.ones), len(hand.twos), len(hand.threes), len(hand.fours), len(hand.fives), len(hand.sixes)}
return 50
else:
return 0
```

```
class YatzyScoresheet:
def score_ones(self, hand):
return sum(hand.ones)
def score_ones(self, hand):
return sum(hand.ones)
def score_ones(self, hand):
return sum(hand.ones)
def score_ones(self, hand):
return sum(hand.ones)
def score_ones(self, hand):
return sum(hand.ones)
def score_sixes(self, hand):
return sum(hand.sixes)
def _score_set(self, hand, set_size):
scores = [0]
for worth, count in hand._sets.items():
if count == set_size:
scores.append(worth*set_size)
return max(scores)
def score_one_pair(self, hand):
return self._score_set(hand, 2)
def score_chance(self, hand):
return sum(hand.ones) + sum(hand.twos) + sum(hand.threes) + sum(hand.fours) + sum(hand.fives) + sum(hand.sixes)
def score_yatzy(self, hand):
if 5 in {len(hand.ones), len(hand.twos), len(hand.threes), len(hand.fours), len(hand.fives), len(hand.sixes)}
return 50
else:
return 0
```

```
def score_yatzy(self, hand):
dicelist = [] #a list to append same value dice
for dice in hand: #looping through to check all dice
dicelist.append(dice)
if dices == hand[0]: #you need to compare all dice
dicelist.append(dice) #only append in list if they are the same
if len(dicelist) == 5: #if that list gets 5 dice of same value = yatzy
return 50
else: #if any of those dice didn't have the same value as hand[0] != yatzy
return 0
```

Courses Plus Student 9,858 PointsAnother option is to review what the _score_set method was doing and borrow that approach. Within that function there is hand._sets.items() which has captured a dictionary of the dice rolls and their associated counts and which we can loop through to find a count of 5.

```
def score_yatzy(self, hand):
for worth, count in hand._sets.items():
if count == 5:
return 50
return 0
```

Hopefully this helps in seeing the solution in a different way.

3,223 PointsAnother solution

```
def score_yatzy(self, hand):
for die in hand:
if hand.count(die) >= 5:
return 50
return 0
```

Here is my solution: ''' def score_yatzy(self, hand): if hand[1:] == hand[:-1]: return 50 else: return 0 '''

12,895 PointsWhy are you appending twice? dicelist.append(dice)

Is that a typo?
