Add your function below!

def average(numbers):
total=sum(numbers)
total=float(total)
total=total/len(numbers)
return total
def get_average(student):
homework=average(student["homework"])
quizzes=average(student["quizzes"])
tests=average(student["tests"])
return .1*homework+.3*quizzes+.6*tests
def get_letter_grade(score):
if score>=90:
return "A"
elif score>=80 and score<=89:
return "B"

elif score>=70 and score<=79:
    return "C"
elif score>=60 and score<=69:
    return "D"
elif score<=59:
    return "F"

print get_letter_grade(get_average(lloyd))
def get_class_average(students):
results=[]
for student in "class":
results.append(get_average(students))
return average(results)
