15. Sum of Divisors

Write a Python program to return the sum of all divisors of a number.

Sample Solution:

Python Code:

def sum_div(number):
    divisors = [1]
    for i in range(2, number):
        if (number % i)==0:
            divisors.append(i)
    return sum(divisors)
print(sum_div(8))
print(sum_div(12))

Sample Output:

7
16
