# Class average is getting calcuated wrong!

#1

Hi
Thanks for codeacademy for giving me a great learning.

Getting below error:
Oops, try again. get_class_average([alice]) returned 80.55 instead of 91.15 as expected
`
My code is

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]
}

clas1 = [lloyd, alice, tyler]

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

def get_average(student):
homework = average(student["homework"])
quiz = average(student["quizzes"])
test = average(student["tests"])
return 0.1 * homework + 0.3 * quiz + 0.6 * test

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 stud in students:
print stud
results.append(get_average(stud))
print results
print average(results)

get_class_average(clas1)

#2
``````clas1 = [lloyd, alice, tyler]
# ...
def get_class_average(students):
results = []
for stud in students:
print stud
results.append(get_average(stud))
print results
print average(results)

get_class_average(clas1)``````

I believe the SCT is quite intent on there being a `students` list.

Instructions
Finally, print out the result of calling `get_class_average` with your `students` list. Your students should be `[lloyd, alice, tyler]`.
Then, print the result of `get_letter_grade` for the class's average.

``````students = [ lloyd, alice, tyler ]

def get_class_average(pupils):
sum = 0
for pupil in pupils:
avg = get_average(pupil)                           # not asked for
glg = get_letter_grade(avg)                        # but it will still
print "%s: %.2f => %s" % (pupil['name'],avg,glg)   # pass the SCT
sum += avg
return sum / len(pupils)

class_bar = get_class_average(students)
print class_bar
