Lesson 8: part of the whole, what am I doing wrong?


#1

The posts here helped me fix a couple issues, but I am still getting this error:

Oops, try again. get_class_average([alice]) should return a number

Here is my 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]
}

# 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 * .10 + quizzes * .3 + tests * .6)
    
def get_letter_grade(score):
    if score >= 90.0:
        return 'A'
    elif score >= 80.0:
        return 'B'
    elif score >= 70.0:
        return 'C'
    elif score >= 60.0:
        return 'D'
    else:
        return 'F';

get_letter_grade(get_average(lloyd))



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

What am I doing wrong?

This line should not be inside the loop.

Thank You!

I actually kept digging and just figured that out from another post. I was coming back here to delete this one. Such a simple, easy thing and it's been giving me a headache for a few hours now.

A post was split to a new topic: Why the below one is not working for me
