im getting this error: `get_class_average([alice]) resulted in an error: list indices must be integers, not dict`

``````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",

"quizzes": [0.0, 75.0, 78.0],
"tests": [100.0, 100.0]
}

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

def get_average(student):
homework = average(student['homework'])
quizzes  = average(student['quizzes'])
tests    = average(student['tests'])

homework *= 0.1
quizzes  *= 0.3
tests    *= 0.6
return homework + quizzes + 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:
results.append(get_average(students[student]))
return average(results)``````

`student` will contain each student, look:

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

so you can just get the average for student, no need to access the students list by index

I already had this resolved but somehow the platform got me back to this. And I can't make it work anymore. Any help? The error is: Oops, try again. get_class_average([alice]) should return a number

Never matter. I solved it in the end.
