Program to determine whether a given number is an abundant number

Java program

import  java.util.*;  
public  class Abundant_number {  
    public static void main(String[] args) {  
        System.out.println("Enter the number?");  
        Scanner sc = new Scanner(System.in);

    int sum = 0;

Python Program:

def is_abundant(n):  
    fctr_sum = sum([fctr for fctr in range(1, n) if n % fctr == 0])  
    return fctr_sum > n  
a = int(input("Enter the number?"));  
if is_abundant(a):  
    print("The number is Abundant.");  
else:  
    print("The number is not Abundant.")  

Output:

Enter the number?24
The number is Abundant.
