Just Weight and See - get_average(alice) raised the following error: global name 'sudents' is not defined


#1

I don't know what to do with this error:
get_average(alice) raised the following error: global name 'sudents' is not defined

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):
    sum(numbers)
    total = sum(numbers)
    return float(total) / len(numbers)

def get_average(student):
    homework = average(sudents["homework"]) * 0.1
    quizzes = average(sudents["quizzes"]) * 0.3
    tests = average(sudents["tests"]) * 0.6
    avg = homework + quizzes + tests
    return avg

is the code I used; I tried adding a "students" list:

students = [lloyd, alice, tyler]

but that didn't help


#2

I think you might wanted to use students here instead of sudents. That together with this:

should solve it.


#3

that fixed one problem, but now it's saying

get_average(alice) raised the following error: list indices must be integers, not str

so I think I need to remove the double quotation marks


#4

There is no think, only try.


#5

did that, now it says

get_average(alice) raised the following error: local variable 'homework' referenced before assignment


#6

For indexing (between brackets []), you still need the quotation marks.


#7

now it's back to "list indicies must be integers, not str"


#8

That's because you're calling it on students, which is an array. You want to call it on an individual student. You'll have to think about how to fix that.


#9

def get_average(student):
    homework = average(student["homework"]) * 0.1
    quizzes = average(student["quizzes"]) * 0.3
    tests = average(student["tests"]) * 0.6
    avg = homework + quizzes + tests
    return avg

that works
