No `score_yatzy` method

I have the method defined in the code. Why got this error:

scoresheets.py 
class YatzyScoresheet:
    def score_ones(self, hand):
        return sum(hand.ones)

    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)

    def score_yatzy(self, hand):
        for w, c in hand._sets.item():
            if count == 5:
                return 50
            else:
                return 0

Hi Peter,

If it says there's "no method", there's a syntax error.

Is it: for w, c in hand._sets.item(): this line? Should it be items()?

Yes, that moves the error along. Next it says there's no count - that's because you've used c in this loop.

Then there's a new error that I've not figured out yet!

OK - I familiarised myself with this challenge.

I don't think you need to use a loop here. If you use the _score_set() method and pass in your hand and the number 5; if that comes back truthy, you have five identical hands. You could also test the length of the set (hand) as if it has a length of 1, there are five identical elements, i.e. one unique entry.

The first method is probably a little clearer as that's its purpose! Something like:

if self._score_set(hand, 5):
  # do the relevant returning

I hope that helps.

Steve.
