Student Becomes the Teacher help

need help with code
this error keeps poping up
I don't know what to do.

``````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):
sum(numbers)
total = sum(numbers)
total = float(total)
total = total / len(numbers)
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:
results.append(get_average(student))
return average(results)
print get_class_average(students)``````

#2

this code:

``````    print get_letter_grade(get_average(lloyd))
def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
return average(results)
print get_class_average(students)``````

the indention is off. The function call should be outside the function and the `get_class_average` function should be after (outside) the get_letter_grade function

#3

sorry I don't understand what you mean.
this error keeps coming up

#4

look:

``````def example_one():
def example_two():
print True``````

look , i nested example_two inside example_one. which is what you did (you nested get_class_average in get_letter_sccore), but the function should be after each other:

``````def example_one():
print True
def example_two():
print True``````

also, make sure the function calls have no indent so they are outside the function

#5

I think I fixed that problem but another one came up.

``````def get_class_average(students):
results = []
for student in students:
results.append(get_average(students))
return average(results)
print get_class_average(students)``````

now its saying this:
get_class_average([alice]) resulted in an error: list indices must be integers, not str

#6

the function call:

``print get_class_average(students)``

should be outside the function (hint, indention, or rather, no indention)

here:

``get_average(students)``

get_average is designed to calculate the average grade for one student. which is why you loop over `students`, the individual students are then stored in `student`
