Oops, try again. get_average(alice) raised the following error: sum expected at most 2 arguments, got 3

1) Code is sensitive to even very small changes. Take care that it is represented accurately in your post.
2) You've got an error message describing a problem about your code. What are your thoughts about that error message, what prevents you from fixing the problem that it describes? (What information are you missing/looking for? What have you considered about what it's saying?)

#3

Try to change your code from:

`grade = sum(homework, quizzes, tests)`

to

`grade = homework + quizzes + tests`

#4

Why calculate homework, quizzes and tests twice? You can make your code shorter

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])

``````grade = 0.1*homework + 0.3*quizzes + 0.6*tests
