Perfect number Program In Python

      

         Check whether a given number is perfect number or not

 In Python

Program to check whether a given number is a perfect number or not is discussed here. A perfect number is a number which is equal to the sum of its proper positive divisors.

For example, 6 is a perfect number.
The divisors of 6 are 1, 2 and 3.
1 + 2 + 3 = 6.

Program:

n = int(input("Enter a number : "))

sum = 0

for i in range (1,n):

    if(n % i == 0):

        sum = sum + i

if(sum == n):

    print(n,"is a perfect number")

else:

    print(n,"is not a perfect number")

OutPut:

Enter a number : 6

6 is a perfect number

Enter a number : 123

123 is not a perfect number
