Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

The code looks right to me, its taking the averages for each student and appending them to the list results. Is it forgetting the third student somehow?

```
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)
return total / len(numbers)
def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
return homework*0.10 + quizzes*0.30 + tests*0.60
def get_letter_grade(score):
if score >= float(90):
return 'A'
elif score >= float(80):
return 'B'
elif score >= float(70):
return 'C'
elif score >= float(60):
return 'D'
else:
return 'F'
result = get_letter_grade(get_average(lloyd))
print result
def get_class_average(students):
results = []
for student in students:
avg = get_average(student)
results.append(avg)
return average(results)
```
