Part of the Whole problem. Please help


#1

I didn't change the old code. Just define a function get_class_average()

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)
    return float(total) / len(numbers)
def get_average(student):
    student["homework"] = average(student["homework"])
    student["quizzes"] = average(student["quizzes"])
    student["tests"] = average(student["tests"])
    return (student["homework"] * 10 + student["quizzes"] * 30 + student["tests"]*60) / 100
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"
# Addional function
def get_class_average(students):
    results = []
    for student in students:
        results.append(get_average(student))
    return average(results)

==> And receive a notification:

Oops, try again. lloyd does not seem to contain the correct dictionary, it should contain: {'quizzes': [88.0, 40.0, 94.0], 'tests': [75.0, 90.0], 'name': 'Lloyd', 'homework': [90.0, 97.0, 75.0, 92.0]}


#2

here:

    student["homework"] = average(student["homework"])
    student["quizzes"] = average(student["quizzes"])
    student["tests"] = average(student["tests"])

this will change the homework, quizzes and tests grades (which are currently a list) into the average of the lists, don't do this. We don't want to design our program this way

Thanks, I understood
