Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

should return 85.85

Hi this line

return average(results)

should be indent like the for loop in the function

Add your function below!

def average(numbers):
total=sum(numbers)
total=float(total)
avg=total/len(numbers)
return avg
def get_average(student):
homework=average(student["homework"]),
quizzes=average(student["quizzes"]),
tests=average(student["tests"]),
return int (0.1 * average(student["homework"]) + 0.3 * average(student["quizzes"]) + 0.6 * average(student["tests"]))
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))
    #print results
    globvar = results
    print globvar
return results

print get_class_average(students)
print "Lloyd, Alice, Tyler"
for k in globvar:
m=[]
m.append( get_letter_grade (globvar))
print m
My code is not working . showing "Oops, try again. get_class_average([alice]) should return a number" error. Can someone help me
