Just Weight and See


#1

Could someone please help? I am quite confused by the error I am receiving... I am stuck on the "Weight and See" Problem, where the goal is to calculate each students weighted grade through homework, quizzes and tests. I am receiving no error in the comment box (it simply says "None"), but every time I submit, codeacademy pops up with the error: "get_average(alice) raised the following errors: list indices must be integers, not str"

What I am confused by is that it seems to be making it through Lloyd well enough??

My code looks like:

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]
}

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

Thank you!

Funny, when I pasted your code the error said
Oops, try again. get_average(alice) raised the following error:
global name 'students' is not defined

So then I saw it! On tests = average(students["tests"]) you used students, after I corrected that it passed.

Start by finding the average of each item and then weigh them at the end.

def get_average(student):
homework= average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(students["tests"])
return homework*.1 + quizzes*.3 + tests*.6

Also idk why it is not indenting but everything after def must be indented
