Firstly , my code runs just fine, but No matter what i change

Alice's tests and homework to, she always gets an A.

I expected her grade to change. Code below.

```
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": [10.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],
"tests": [10.0, 10.0]
}
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 (0.1 * homework + 0.3 * quizzes + 0.6 * 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"
print get_letter_grade(alice)
Look at Alice's grade, why does she always get an A
