# 8. Part of the Whole

#1

Hi, can anyone help me with this, I got the following error : "Oops, try again. get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected"

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]
}

class_list = [lloyd, alice, tyler]

def average(numbers):
total= sum(numbers)
total = float(total)
total = total/len(numbers)

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
return 0.1* homework + .3* quizzes + .6*tests

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 class_list:
results.append(get_average(student))

return average(results)``````

here:

``for student in class_list:``

why do you loop over class_list?
