Part of the whole, 8/9

Everything except printing the class average works. I've tried print get_class_average(student), print get_class_average(get_average(lloyd), print get_class_average(students), and print get_class_average(get_class_average(lloyd), get_class_average(alice), get_class_average(tyler)), but none of them have worked.

```
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(lst):
return float(sum(lst)) / len(lst)
def get_average(student):
for key in student:
h = average (student["homework"])
q = average (student["quizzes"])
t = average (student["tests"])
aver = (h*0.1) + (q*0.3) + (t*0.6)
return aver
def get_letter_grade(score):
if score >= 90:

elif score >= 70:

elif score >= 60:
return "D"
else:
return "F"
def get_class_average(students):
results = []
for student in students:
get_average(student)
results.append(get_average(student))
return average(results)
```
