PLEASE HELP - I CAN't GO ANY FURTHER THEN THIS -

KEEP GETTING THIS MESSAGE - Oops, try again. Did you remember to print the average of the class? It looks like "83.8666666667" wasn't printed.

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!

def average(numbers):

total = sum(numbers)

total = float(total)

total = total / len(numbers)

return total

def get_average(student):

homework = average(student['homework'])

quizzes = average(student['quizzes'])

tests = average(student['tests'])

return 0.1 * average(student['homework']) + \

0.3 * average(student['quizzes']) + 0.6 * average(student['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'

get_letter_grade = get_average(lloyd)

print get_letter_grade(get_average(lloyd))

def get_class_average(students):

results = []

for student in students:

result = get_average(student)

results.append(result)

return average(results)

```
students = [lloyd, alice, tylor]
print get_class_average(students)
print get_letter_grade(get_class_average(students))
IF CAN'T GET PAST THIS - I AM OUT - I SIMPLY DON'T UNDERSTAND WHY THAT MESSAGE.
```
