class Customer(object):
def __init__(self, idnumber, review):
self.idnumber = idnumber
self.reviews = [review]
def addReview(self, review):
self.reviews.append(review)
def averageGrade(self):
tot = 0
for review in self.reviews:
tot += review.grade
return tot / len(self.reviews)
def av_grade(self):
return reduce(lambda x, y: x.grade+y.grade, self.reviews)
now,the function is pointless and incorrect but av_grade doesn't work.
why can't i use reduce like this?
