I keep getting this error message: Oops, try again. get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected.

My code looks like this:

``````lloyd = {
"name": "Lloyd",
"homework": [90.0, 97.0, 75.0, 92.0],
"quizzes": [88.0, 40.0, 94.0],
"tests": [75.0, 90.0]
}
alice = {
"name": "Alice",
"homework": [100.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],
"tests": [89.0, 97.0]
}
tyler = {
"name": "Tyler",
"homework": [0.0, 87.0, 75.0, 22.0],
"quizzes": [0.0, 75.0, 78.0],
"tests": [100.0, 100.0]
}

class_list = [lloyd, alice, tyler]

def average(numbers):
total = sum(numbers)
total = float(total)

def get_average(student):
homework = average(student["homework"])
quizzes = average(student['quizzes'])
tests = average(student['tests'])
weighted_average = (homework*0.1) + (quizzes*0.3) + \
(tests*0.6)
return weighted_average

if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"

def get_class_average(students):
results = []
for student in class_list:
results.append(get_average(student))
return average(results)``````

Any help would be appreciated... Been stuck for a while now....

you should loop over `students`, so you can calculate a class average for one student, two students (any combi) or all three students

Thanks for the quick reply, but I don't understand...

here:

``def get_class_average(students):``

`students` contains a list, so you should loop over students. This way, you can call your function with one, two or three students
