Okay, I’ve been going through all the other topics like this one but I have found no answer that can solve my problem - so I decided I will upload my problem personally as I cannot find the error within my code.

The code that I’ve written gave me the error: “get_class_average([lloyd]) returned 85.85 instead of 80.55 as expected” - so I can only guess it’s an arithmetic error that lies within the code, not the semantics itself

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]
}
results = []
# Add your function below!
def average(numbers):
total = float(sum(numbers))
total /= len(numbers)
return total
def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
homework = homework * 0.1
quizzes = quizzes * 0.3
tests = tests * 0.6
return (homework + quizzes + 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"
def get_class_average(class_list):
for students in class_list:
results.append(get_average(students))
return average(results)
print get_letter_grade(get_average(lloyd))```
```
