Please help. Error:Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade

`python

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]
}

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

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"])*0.1
quizzes=average(student["quizzes"])*0.3
tests=average(student["tests"])*0.6
print homework+quizzes+tests
return homework+quizzes+tests

def get_letter_grade(score):
if 90<=score:
return "A"
elif 80<=score:
return "B"
elif 70<=score:
return "C"
elif 60<=score:
return "D"
else:
return "F"

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

print get_class_average(students)
print get_letter_grade(get_class_average(students))`

here:

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

why does your students list contain strings?
