Hi all, i have a problem with my code, when i try to run it i have this message: get_class_average[alice,lloyd] returned 91.15 instead of 85.85 as expected. i have no idea why is this happened, hope someone can help me.


Replace this line with your code. 

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)/len(numbers)
    return total
   
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    return 0.1 * average(student["homework"]) +  0.3 * average(student["quizzes"]) +  0.6 * average(student["tests"])
    
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:
        results.append(get_average(student))
        return average(results)


#2

a function ends the moment a return keyword is reached

If a return keyword is reached in a loop, the loop will break in order for the function to end
