Add your function below!

def average(numbers):
total= sum(numbers)
total = float(total)
total = total / len(numbers)
return total
def get_average(students):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])

homework = 0.1 * average(student["homework"])
quizzes =  0.3 *average(student["quizzes"])
tests = 0.6 *average(student["tests"])

grade = sum(homework, quizzes,  tests)

print grade

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

return grade
