Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected


I dont know what is wrong about it i thing i am right


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]
}

# Add your function below!
def average(numbers):
    total = sum(numbers)
    total = float(total)
    return total / len(numbers)
    
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    return homework*0.1+quizzes*0.3+tests*0.6
    
def get_letter_grade(score):
    if score >= 90:
        return "A"
    elif score >= 80:
        return "B"
    elif score >= 70:
        return "C"
    elif score >= 60:
        return "D"
    else:
        return "F"
                
print get_letter_grade(get_average(lloyd))

students = [lloyd, alice, tyler]

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

Two things:
1.return statement halts a function the moment function reaches it so your function halts after first iteration.

2.So Inside the function get_class_average()
The final return statement should not be part of for loop but its a separate block of code inside the function and it should have same level of indentation as for loop.

also this line of code is idle there and does nothing.

get_average(student)
