Transform code to list perfect numbers from for loop to while loops

Question

I am supposed to write a Python program that will identify and print all the perfect numbers in some closed interval [2, n], one per line.

We only should use nested while loops and if-else statements. I did it somehow using a for loop, but can't figure out the same using a while loop.

How could I translate my code into a while loop?

Here's what I have:

limit = int(input("enter upper limit for perfect number search: "))

for n in range(2, limit + 1):
    sum = 0
    for divisor in range(1, n):
        if not n % divisor:
            sum += divisor
        if sum == n:
            print(n, "is a perfect number")

Answer 1

This should work:

limit = int(input("enter upper limit for perfect number search: "))

n = 1

while n <= limit:

    sum = 0
    divisor = 1
    while divisor < n:
        if not n % divisor:
            sum += divisor
        divisor = divisor + 1
    if sum == n:
        print(n, "is a perfect number")
    n = n + 1
