# Part of a Whole results don't make sense

My entire code was approved but prints grade A for all students including Lloyd, who should be receiving B (80.55) and then prints class average as B.

A
A
A
83.8666666667
B
None

``````lloyd = {
"name": "Lloyd",
"homework": [90.0, 97.0, 75.0, 92.0],
"quizzes": [88.0, 40.0, 94.0],

def get_average(student):

return homework*0.10+quizzes*0.30+tests*0.60

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(students):
results=[]
for student in students:
results.append(get_average(student))
return average(results)

print get_class_average(students)

You are yet to define your students list.

Also, this line is faulty.

You should be printing the result of get_letter_grade for the get_class_average of students.
