Courses Plus Student 3,923 PointsWant explanation why my code is wrong for the chance scoring challenge
I looked at the previous video and found that count from hand._sets.items() will give how many dice have the same value.
if hand[:] = [one, one, one, one, one] hand._sets.items() will be [(1: 5), (2: 0), (3: 0), (4: 0), (5: 0)].
So I assumed that if I made count in hand._sets.items() == 5 it is equivalent to 5 dice with the same values.
Thus I wrote my code like the following. But when I try this code I get Bummer! Got the wrong score for Yatzy..
What am I failing to see?
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 worth, count in hand._sets.items():
if count == 5:
return 50
else:
return 0

return 0 outside of the for loop so 0 is only returned if no Yatzy found

forloop will run until either:breakstatement is reachedreturnstatement is reachedOn the first iteration, the
ifstatement the value ofcountis compared to 5. If it is equal then 50 is returned.If it's not equal to 5, the
elsestatement is run, and 0 is returned ending the loop.Moving the
return 0outside theforloop will allow the loop to check every value pair then only return 0 if not count is 5.Post back if you need more help. Good luck!!!
