# Getting wrong output for "student becomes the teacher"

#1

there is no error but I am getting wrong output
Oops, try again. get_class_average([alice]) returned 65.55 instead of 91.15 as expected

seems like your quizzes got messed up and left off the .3 on it. Try fixing that!

Oops, try again. get_class_average([alice, lloyd]) returned 80.55 instead of 85.85 as expected

here is my 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 = {
"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)
return float(total) / len(numbers)``````

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

if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"

# student = lloyd

def get_class_average(students):
results = []
for student in students:
get_average(student)

# print get_average(student)

``````    print results
results.append(get_average(student))
return average(results)``````

print get_average(alice)
print get_average(tyler)
