Finding the average from a list

Question

Here's my code

#Gets a list of numbers from user
def get_score():
    score_list = []
    keep_going = 'y'
    while keep_going == 'y':
        score = float(input('Enter a test score: '))
        while score < 0:
            print('Positive numbers only')
            score = float(input('Enter a test score: '))
        score_list.append(score)
        keep_going = input("More scores (y/n) ")
    return score_list

#Finding the average based on user's input 
def calculated_average():
    numbers_of_grades = float(input)
    score_list = [int(s) for s in score_list]
    average = sum(score_list) / len(score_list)
    return average

def main():
    score = get_score()
    average = calculated_average(score)

main()

I'm trying to find the average grade based on the user's input, but it looks like there's something wrong at the calculating average part. I can't seem to figure out how to get the sum of the score_list. Any help is appreciated thanks!

"but it looks like there's something wrong at the calculating average part" - please make your problem statement clear. Give sample input and expected and actual result or error message you are getting. "something wrong" is not very clear — FlyingTeller, Oct 04 '18 at 15:22

Fixed a couple of minor mistakes, basically you only forgot to parse the list of grades to your other function. It should work like this:

#Gets a list of numbers from user
def get_score():

    score_list = []
    keep_going = 'y'

    while keep_going == 'y':

        score = float(input('Enter a test score: '))

        while score < 0:

            print('Positive numbers only')
            score = float(input('Enter a test score: '))

        score_list.append(score)
        keep_going = input("More scores (y/n) ")

    return score_list

#Finding the average based on user's input
def calculated_average(score_list):

    numbers_of_grades = len(score_list)
    score_list = [int(s) for s in score_list]
    average = float(sum(score_list) / len(score_list))

    return average

def main():

    score = get_score()
    average = calculated_average(score)
    print(average)

main()

You should just pass score to calculated_average and then you can simply return sum(x)/ len(x)

def calculated_average(x):
    return sum(x) / len(x)

def main():
    score = get_score()
    print(calculated_average(score))

main()

Enter a test score: 20
More scores (y/n) y
Enter a test score: 10
More scores (y/n) y
Enter a test score: 30
More scores (y/n) n
20.0
