Hi Guys,

Please find the below code which I struggled at the final part and then resolved

```
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
def get_average(student) :
homework = average(student["homework"])
quizzes=average(student["quizzes"])
tests=average(student["tests"])
return (homework * 0.1) + (quizzes * 0.3) + (tests * 0.6)
def get_letter_grade(score) :
if score >= 90 :
return "A"
elif score >= 80 and score < 90 :
return "B"
elif score >=70 and score < 80 :
return "C"
elif score >=60 and score < 70 :
return "D"
else :
return "F"
def get_class_average (students) :
results=[]
for student in students :
results.append(get_average(student))
return average(results)
```
