[Tutor] Question

[Michael Hall]

# 1) a perfect number is a positive integer that is equal to the
# sum of its proper positive divisors,excluding the number itself.
# for example, 6 is a perfect number because it is evenly divisible
# by 1, 2 and 3 - all of it's divisors - and the sum 1 + 2 + 3 = 6.
# a) write a function, getDivisors(), that returns a list of all
# of the positive divisors of a given number. for example -
# result = getDivisors(24)
# print(result)
# would yield: "[ 1, 2, 3, 4, 6, 8, 12]"



def main():

    num = int(input('Please Enter a Number: '))
    getDivisors(num)


def getDivisors(num):
    my_list = []
    sum = 0
    for number in range(1, num, 10000):

        if num % number == 0:
            print([1, 2, 3])
            sum += num


    print('The sum is ', sum)
    if sum == num:
        print(num, 'is a perfect number')
    else:
        print(num, 'is not a perfect number')



main()

Andreas and others "Thank you for your help. I am still having an issues. I
went to the links and they were very helpful. Here is my problem. If you
enter the number 6 the program is just what the teacher wants. My problem
is if you enter any other number it is wrong. AGAIN, I AM NOT. I REPEAT I
AM NOT ASKING YOU OR ANY OF YOU TO WRITE MY PROGRAM OR DO MY HOMEWORK. I am
asking for a solution to the problem. The program has been written I
just need help. Thank you in advance. On Fri, Dec 2, 2011 at 1:55 AM,
