# Student Becomes the Teacher Help

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

I don't know why this message is appearing because it returns what it is supposed to.

``````Replace this line with your code.
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 = {

"homework": [100.0, 92.0, 98.0, 100.0],

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

if score >= 90:
return "A"
elif score >= 80 and score < 90:
return "B"
elif score >= 70 and score < 80:

else:
return "F"
def get_class_average(student):
results = []
for student in student:
results.append(get_average(student))
return average(results)

print get_class_average(student)
print "Lloyd, Alice, Tyler"

this list:

``student = [lloyd, alice, tyler]``

should be named `students`
