In "Student Becomes the Teacher": 8. Part of the Whole,

I keep receiving:

"Oops, try again. get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected"

For some reason, I believe that the code is only taking one person's average and excluding the others.

```
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 = float(sum(numbers))
avg = (total / len(numbers))
return avg
def get_average(student):
homework = float(average(student["homework"]))
quizzes = float(average(student["quizzes"]))
tests = float(average(student["tests"]))
weighted_average = (homework*0.1)+(quizzes*0.3)+(tests*0.6)
return weighted_average
def get_letter_grade(score):
if score >= 90:
print "A"
return "A"
elif score >= 80 and score < 90:
print "B"
return "B"
elif score >= 70 and score < 80:
print "C"
return "C"
elif score >= 60 and score < 70:
print "D"
return "D"
else:
print "F"
return "F"
def get_class_average(student):
results = []
results.append(get_average(lloyd))
results.append(get_average(alice))
results.append(get_average(tyler))
return average(results)
```

I've looked at the other posts addressing this topic and have considered multiple sources of the problem but to no avail. Any and all help would be greatly appreciated. Thank you!
