I have been trying to solve the problem mentioned in the additional exercise since I feel that I am stuck. The problem in question here related to .get_average. here is my code
class Student:
def __init__(self, name, year):
self.name = name
self.year = year
self.grades = []
def add_grade(self, grade):
if type(grade) == Grade:
self.grades.append(grade)
def get_average(self):
self.score = 0
for i in self.grades:
self.score += i
return self.score / len(self.grades)
class Grade:
minimum_passing = 65
def __init__(self, score):
self.score = score
def is_passing(self):
if self.score > self.minimum_passing:
return True
else:
return False
roger = Student("Roger van der Weyden", 10)
sandro = Student("Sandro Botticelli", 12)
pieter = Student("Pieter Bruegel the Elder", 8)
pieter_grade = Grade(100)
pieter.add_grade(pieter_grade)
is_pieter_passing = Grade(100)
print(is_pieter_passing.is_passing())
print(pieter.get_average())
Can someone please help me with my code. Thank you.
It might be wise to read the text that is now at the top of your post . Without a project or a description of your actual task you’ve left an awful lot of guesswork for everyone else. That should probably be changed.
Secondly, you seem to have some code that attempts to get an average? What’s wrong with it? Does it throw errors, does it just supply a value you did not expect? A little background goes a long way- How to ask good questions (and get good answers)
The error is that you are trying to add an object and a number
in the get_average function
on this line: self.score += i (that’s line 14 in the Codebyte)
in the get_average function, you had:
self.score = 0
for i in self.grades:
self.score += i
but self.grades seems to be a list of Grade objects, not a list of numbers
so the i in the for loop is a Grade object, not an int nor a float
In the Grade class, the number you want is stored in the score variable,
so to extract that number you need .score i is an instance of Grade, so it would be i.score
So that line should actually be: self.score += i.score
if you want to make the function even more flexible, you could check the type of i before adding it to self.score with an if statement, and add either i or i.score depending on what the type of i is.
