I'm currently stuck in Student Becomes The Teacher, lesson 8. Part of the Whole.

The feedback is giving me this error:

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

So it seems to be taking in only Alice's average and not adding the others to the results listing.

I cannot figure out why?

```
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)
result= total / len(numbers)
return result
print average (tyler["homework"])
print average (alice["tests"])
def get_average(student):
homework = average(student["homework"])
quizzes = average (student["quizzes"])
tests = average(student["tests"])
endgrade = homework*0.1 + quizzes*0.3 + tests*0.6
return endgrade
print get_average(lloyd)
print get_average(alice)
print get_average(tyler)
def get_letter_grade(student):
score = get_average(student)
if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"
print get_letter_grade (lloyd)
print get_letter_grade (alice)
print get_letter_grade (tyler)
students = [lloyd, alice, tyler]
def get_class_average(students):
results = []
for student in students:
studentaverage = get_average(student)
results.append(studentaverage)
return average(results)
print get_class_average(students)
```
