SyntaxError: invalid syntax

Not sure why my final return function isn't working. Any advice appreciated.

``````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"]) * 0.1
quizzes = average(student["quizzes"]) * 0.3
tests = average(student["tests"] * 0.6
return sum(homework, quizzes, tests)``````

Solved, nevermind

#3

can you please tell me how you solved it as I am stuck and confused how to do this part

#5

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

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

Didin't work for me.

``get_average(alice) returned 80.55 instead of the expected 91.15``

Solved. The `for student in students` was the problem.
