if __name__ == "__main__" :

    # initialisation 
    i = 2;sum = 1;

    # take input from user and typecast into integer
    n = int(input("Enter a number: "))

    # iterating till n//2 value
    while(i <= n//2 ) :

        # if proper divisor then add it.
        if (n % i == 0) :

            sum += i

        i += 1

    # check sum equal to n or not
    if sum == n :
        print(n,"is a perfect number")

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