Part of the Whole


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


Not sure why I don't see tyler, but guess it would work if I did 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)
    divide = total / len(numbers)
    return divide

def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    return 0.10 * average(student["homework"]) + \
    0.30 * average(student["quizzes"]) + \
    0.60 * average(student["tests"])

def get_letter_grade(score):
    if score >= 90:
        return "A"
    elif score >= 80 and score < 90:
        return "B"
    elif score >= 70 and score < 80:
        return "C"
    elif score >= 60 and score < 70:
        return "D"
    else:
        return "F"


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


#2

a function ends the moment a return keyword is reached, if the return keyword is reached in a loop, the loop breaks

Place return outside the loop so the whole loop can run


#3

Thanks for the response. I can go to left any further without an error saying return not in function. Also new error i receive is "Oops, try again. get_class_average([alice, lloyd]) returned 80.55 instead of 85.85 as expected"

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

#4

results should be declared outside the loop, otherwise the list becomes empty each iteration of the loop, while it should persist the data append to it


#5

That did the trick! That was pretty tough for me!
