I can't figure out where is the problem.
So,can I teach me how to fix it ?

``````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]
}

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"])
return 0.1*homework + 0.3*quizzes + 0.6*tests

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

students = (lloyd,alice,tyler)

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

After I exucute this program,following message appear
"Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected"

#2

get_class_average should return average value of students' average grades, however in your code function doesn't return average value of results

This part needs improvement

#3

I fixed mentioned part,the problem is solved.

def get_class_average(students):
results = []
for student in students:
return results.append(get_average(student))
Thank you so much
