get_average(alice) returned 86.55 instead of the expected 91.15


#1

Continuing the discussion from 6. Just Weight and See:

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

gives me an error "get_average(alice) returned 86.55 instead of the expected 91.15"

I don't know what I am doing wrong

@cpm1627,

Have a close look at

homework = average(student["homework"])

quizzes = average(student["quizzes"])

tests = average(student["quizzes"])

Same problem here...


#4

Found it!

tests = average(student["quizzes"])

should say:

tests = average(student["tests"])
