I have a problem with this extra exercise.
Question : Write a
get_average() that returns the student’s average score.
so I wrote the code as follows.
class Student: def __init__(self, name, year): self.name = name self.year = year self.grades =  def add_grade(self, grade): self.grades.append(grade) def get_average(self): total = 0 for grade in self.grades: total += grade return total / len(self.grades) roger = Student("Roger van der Weyden", 10) sandro = Student("Sandro Botticelli", 12) pieter = Student("Pieter Bruegel the Elder", 8) pieter.add_grade(90) pieter.add_grade(100) pieter.add_grade(80) print(pieter.grades) print(pieter.get_average())
And I got a result like this.
[90, 100, 80]
pieter.grades shows that I have done correctly to have each score appended to pieter.grades
However, I don’t know why the average is wrong. It should be 90.0 but it seems to be only the first element divided by 3.
