Problems with "while" looping

Question

I have to somehow do a function in which when I execute it I will be able to add all the divisors of a number, in the way shown below.

This is getting me crazy, I have been in the same problem for about an hour.

def sum_divisors(n):
  # Return the sum of all divisors of n, not including n
  divisor = 1
  while divisor < n:
    if n%divisor==0:
      return divisor
      divisor = divisor + 1
    else:
      divisor = divisor + 1

print(sum_divisors(6)) # Should be 1+2+3=6
print(sum_divisors(12)) # Should be 1+2+3+4+6=16

Answer 1

def sum_divisors(n): 
    sum = 0
    z = 1

    while n > z:
        if n % z == 0:
            sum = sum + z
            z = z + 1
        else:
            z = z + 1
    # Return the sum of all divisors of n, not including n
    return sum

Answer 2

In your fonction, you return instantly after finding a divisor. That's why your fonction doesnt work Try to put each n%divisor == 0 in a list ans return it AT the end of the while.

Or try to print it directly.
