In number theory, 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.

def perfectnumber(numbr): s=0 i=1 while(i<=10000): temp=numbr%i if(temp==0 and i!=numbr): s+=i i+=1 if(s==numbr): return 1 else: return 0 numbr=int(input('Enter a Number : ')) if(perfectnumber(numbr)==1): print("The number is a perfect number") else: print("The number is not a perfect number")
