I'm doing the Student Becomes The Teacher exercise.

https://www.codecademy.com/courses/python-beginner-en-qzsCL/1/4?curriculum_id=4f89dab3d788890003000096

I keep getting an error stating the total for Alice is coming out at 79.9 rather than 91.15 as it's supposed to be. I've verified the numbers I am using, and they are correct. I calculated by hand and I get 91.15. The 79.9 is the total for Tyler, below Alice. I've tried swapping Tyler's and Alice's numbers, but the computer catches it.

Here is my code:

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

Please help!
