Python program to check number is perfect number or not

Write a Python program which accept a integer number form user and check number is perfect or Not.

A perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself.

Perfect Numbers between 1 to 10000 are:

6,28,496,8128

Solution:

num=int(input("Enter any Number : "))
sum=0
for a in range (1,num):
    if num%a==0:
        sum=sum+a
if sum==num:
    print(num ," is Perfect Number")
else:
    print(num ," is not a Perfect Number")

Enter any Number : 7

7  is not a Perfect Number

========================
