Hi guys,

I just can't figure out what I'm doing wrong - my code seems identical to previous posters. Error message: "get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected"

Help Please!!!

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!

print get_letter_grade(get_average(lloyd))

students = [lloyd,alice,tyler]

def get_class_average(students):

for student in students :

results.append(get_average(student))

return average(results)

print get_class_average(students)
