I want to know what’s wrong with my code?and where my thought process got wrong? thank you so much

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)
total = total/len(numbers)
def get_average(student):
homework = average(student[“homework”])
quizzes = average(student[“quizzes”])
tests = average(student[“tests”])
sums = sum(3*(homework + quizzes + tests))
return sums

Hi @wonderliu,

The instructions state …

Multiply the 3 averages by their weights and return the sum of those three. Homework is 10%, quizzes are 30% and tests are 60%.

However, you have this …

``````       sums = sum(3*(homework + quizzes + tests))
return sums
``````

The above multiplies the sum of the averages by `3`, which is not the same as multiplying each one by its weight.

To multiply each of the averages by their weights and `return` the sum of those weights, just do this …

``       return 0.1 * homework + 0.3 * quizzes + 0.6 * tests``
