A perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. For instance, 6 has divisors 1, 2 and 3, and 1 + 2 + 3 = 6, so 6 is a perfect number. other example are 28, 496, and 8,128.

Program:

n =int(input("Enter any number: ")) sum=0 for i in range(1, n): if(n % i == 0): sum = sum + i if (sum == n): print("The number is a Perfect number!") else: print("The number is not a Perfect number!")

Output:

Enter any number: 6 The number is a Perfect number!
