# Just weight and see

My code:

``````lloyd = {

return sum``````
``error:``

Make sure you have defined get_average

I have defined the function but still it is telling me that i have not defined it.

#2

you nested the get_average function inside the average function, the get_average function should be outside/after average function (hint: indent)

#3

Thanks for the help. I understood it. But still my code is not working.

This 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]
}

numbers=[1,2,3,4,5]
def average(numbers):
total=sum(numbers)
a=float(total)/len(numbers)
return a

student=[lloyd,alice,tyler]

def get_average(student):

homework=average(["homework"])

quizzes=average(["quizzes"])

tests = average(["tests"])

homework=homework*0.1
quizzes=quizzes*0.3
tests=tests*0.6
sum=homework+quizzes+tests
return sum``````

error:
get_average(alice) raised the following error: unsupported operand type(s) for +: 'int' and 'str'

#4

I got the error. thanks anyways!!!

#5

if we add an function call:

``get_average(alice)``

we can actually see where there is interpreter error

here:

``````    homework=average(["homework"])

quizzes=average(["quizzes"])

tests = average(["tests"])``````

you call `average()`, `average` is designed to calculate the average of a list of numbers, `["homework"]` clearly isn't a list with numbers, maybe you want to calulate the average for the student homework grades?

#6

yes I had to calculate average of student homework

this is my code:

def get_average(student):

``````homework=average(student["homework"])

quizzes=average(student["quizzes"])

tests = average(student["tests"])

homework=homework*0.1
quizzes=quizzes*0.3
tests=tests*0.6
sum=homework+quizzes+tests
return sum``````

that looks good, all sorted now?

#8

ya its sorted now. It worked!!!
