Perfect numbers

[MPKenley]

Description
A perfect number is a positive integer that is equal to the sum of its proper divisors (also positive integer) excluding itself.
Here's two examples of perfect numbers:
1,2 and 3 are proper divisors of 6. Then 6= 1+2+3
1,2,4,7,14 are all proper divisors of 28. Then 1+2+4+7+14

Behavior
Write a python program that takes a set of positive number and returns all the perfect numbers that is that list.

Precision:

• create a list of natural numbers from 1 to 1000
• Iterate over this and use the function to check if the numbers are perfects.
• Return a list of all perfect numbers within this range

Tests

• Ensure that the function correctly identifies the divisors of a number.
  Example
  28 are [1,2,4,7,14]

• Test the program with edge cases like 1,0, or negative numbers and handle invalid input types like strings or none.

• Running the function multiple times with the same input should always yield the same output.
