Python program to calculate the sum of elements in a list

This is a Python program which calculates the sum of all the elements in a list. Here we use a function called sum() to calculate the sum of all the items in a list.

PROGRAM : 

lst = []
num = int(input('How many numbers: '))
for n in range(num):
    numbers = int(input('Enter number '))
    lst.append(numbers)
print("Sum of elements in given list is :", sum(lst))

OUTPUT : 

Python  - Sum of all items in a list

Java Program to calculate the Sum of Elements in an Array

This is a Java Program which calculates the sum of all elements in an array.

Here initially first element in array and  0 are added the obtained sum is added to 2nd element and so on until the last element in the array.

PROGRAM :

package codingcorner.in;

import java.util.Scanner;

public class SumOfElementsArray {
 public static void main(String[] args) {
  int i, n, sum = 0;
  Scanner scan = new Scanner(System.in);
  System.out.print("How many elements do u want to add ?\t");
  n = scan.nextInt();
  int array[] = new int[n];
  for (i = 0; i < n; i++) {
   System.out.print("\nEnter number" + (i + 1));
   array[i] = scan.nextInt();
  }
  scan.close();
  for (i = 0; i < n; i++) {
   sum = sum + array[i];
  }
  System.out.print("\nThe sum of " + n + " numbers is " + sum);
 }
}
