Student Becomes the Teacher - Part of the Whole issues


#1

HALP. I have no idea what I'm getting wrong!

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) / len(numbers)
    return total
    
def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    return 0.1 * homework + 0.3 * quizzes + 0.6 * tests
    
def get_letter_grade(score):
    if score >= 90.0:
        return "A"
    elif 80.0 <= score < 90.0:
        return "B"
    elif 70.0 <= score < 80.0:
        return "C"
    elif 60.0 <= score < 70.0:
        return "D"
    else:
        return "F"
        
def get_class_average(students):
    classroom = [lloyd, alice, tyler]
    results = []
    for student in classroom:
        results.append(get_average(student))
    return average(results)

It's returning the following error:

Oops, try again.
get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected

Whyy?


#2

why did you define the classroom inside the function , also you iterate for each student in classroom ??


#3

I didn't do it for any reason in particular, just went following the instructions, and it ended up like that.

And the question does ask:

For each student item in the class list, calculate get_average(student) and then call results.append() with that result.

So I just followed along with what it requested to do.


#4

yes i know , but you wanna use this function for every classroom , not a single classroom how has lloyd, alice, tyler
so the instruction tell to iterate for each student in class; ( the class is a list of students )
and the list of students you entered to the function is students

our code will be :
for student in students:

Oh, wow, okay, thank you, that actually went through without any trouble.

Thank you very much!
