error message:

get_average(alice) returned 93.4 instead of the expected 91.15

the code:

``````lloyd = {

"quizzes": [88.0, 40.0, 94.0],

def average(numbers):

def get_average(student):
homework = average(student['homework']) * 0.6

sum = homework + quizzes + tests
return sum

Check the indentation of your methods, specifically the returns

#3

Check the instructions. More specifically, look at the weighted factor values for each of the scores:

Homework is 10%, quizzes are 30% and tests are 60%.
