Please help, I've been struggling for the past hour in fiding out what goes wrong. Here is the error message:
Oops, try again. get_average(alice) raised the following error: can't multiply sequence by non-int of type 'float'

``````Replace this line with your code.
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],

"quizzes": [0.0, 75.0, 78.0],
"tests": [100.0, 100.0]
}

def average(numbers):
total = sum(numbers)
total = float(total) / len(numbers)

def get_average(student):
homework = average(student["homework"]),
quizzes = average(student["quizzes"]),
tests = average(student["tests"]),
total = 0.1 * homework + 0.3 * quizzes + 0.6 * tests

Solution found - misused commas - removing all commas from the get_average function solved the issue.

}

def average(numbers):
total=sum(numbers)
total=float(total)
result=total/len(numbers)
return result

def get_average(alice):
homework=alice['homework']
quizzes=alice['quizzes']
tests=alice['tests']
averageHomework=sum(homework)/len(homework)
averageQuizzes=sum(quizzes)/len(quizzes)
averageTests=sum(tests)/len(tests)
result=(0.1*averageHomework)+(0.3*averageQuizzes)+(0.6*averageTests)
print result

Why do a variable total?

why not return it immediatly?
And you don't need those commas in the get_average function
code:

``````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``````
