# How is everyone doing

it keeps saying something
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

``````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"])

weighted_homework = homework * 0.10
weighted_quizzes = quizzes * 0.30
weighted_tests = tests * 0.60

return weighted_homework + weighted_quizzes + weighted_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)
results = get_class_average([lloyd, alice, tyler])

print(results)

#2

the `students` list which you build in 3. put it together is missing.

#3

i dont understand you. what line

#4

in 3. put it together, you build a list. You need it to pass this exercise
