Just weight and see


#1

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(lloyd["homework"]+alice["homework"]           +tyler["homework"])
       
        quizzes=average(lloyd["quizzes"]+alice["quizzes"]              +tyler["quizzes"])
       
       
       
       
        tests = average(lloyd["tests"]+alice["tests"] +tyler["t         ests"])
        
        homework=homework*0.1
        quizzes=quizzes*0.3
        tests=tests*0.6
        sum=homework+quizzes+tests
        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

#7

that looks good, all sorted now? :slight_smile:


#8

ya its sorted now. It worked!!!
