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

who can kindly help me pointing the error? I am doing it for a day...


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

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)


#2

a function ends the moment a return keyword is reached

if a return keyword is reached in a loop, the function still needs to end, so the loop will break

so, your loop breaks in its first iteration

Thanks a lot. I change the place of "return" like following. And I succeed.
