Getting the should return a number message for alice even though after checking returned data number is there.

Code appears to be working correctly but continue to get error message:
Oops, try again. get_class_average([alice]) should return a number

Won't let me past error even though results look correct

data received in results : [80.55, 91.15, 79.9]

Hello, I am also getting the same error message.

here is my 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],
"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]
}

Add your function below!

students = [lloyd, alice, tyler]

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

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

def get_letter_grade(score):
if score>=90:
return "A"
elif score>=80:
return "B"
elif score>=70:
return "C"
elif score>=60:
return "D"
else :
return "F"

fin = get_letter_grade(get_average(lloyd))

print fin

def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
return results

@raghuvk,
Using

    results.append(get_average(student))
 return results

results is an Array.....
so try using
return sum(results);


#5

try return average(results) to get the class average

Had the same, the return should not be indented, cause else it will return every time a student goes through the function.
it should only return if the for loop is over -> meaning all the students are in the list and the average can be calculated. Hope this helps
