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

I can't find what i'm doing wrong but it keeps saying the same error message,help please

``````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]
}

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

def get_average(student):
homework=average(student["homework"])
quizzes=average(student["quizzes"])
tests=average(student["tests"])
return 0.1 * homework + 0.3 * quizzes + 0.6 * 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 students:
student_average=get_average(student)
results.append(student_average)
return average(results)
print get_class_average([lloyd,alice,tyler])

#2

the list with students which you build in 3. put it together is missing, and you need it to pass this exercise

#3

If you create the students `list` and send it as a parameter it works fine.

#4

thanks a lot,it works

#5

@root4af is right, once you created the list you can supply students as argument instead of having to code the list every time.
