I get an error message sayin that lloyd's average is 85.55 when it expected 80.55, but then I printed get_average(lloyd) and it returned the correct average

```
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]
}
students = [lloyd, alice, tyler]
results = []
# Add your function below!
def average (numbers):
total = sum(numbers)
total = float(total)
total = total/ len(numbers)
return total
def get_average(student):
homework = average(student['homework'])
quizzes = average(student['quizzes'])
tests = average(student['tests'])
grade = (homework*0.1)+(quizzes*0.3)+(tests*0.6)
return grade
def get_letter_grade(score):
if score >= 90:
return 'A'
if score >= 80:
return 'B'
if score >= 70:
return 'C'
if score >= 60:
return 'D'
else:
return 'F'
def get_class_average(students):
for student in students:
results.append(get_average(student))
return average(results).
