## Approach 1

In the first approach we’ll loop through the elements of the array and add every element to the sum which is initialized to 0.

arr = [1,2,3,4,8,9] sum = 0 for element in arr: sum = sum + element print("sum of array elements is ", sum)

Output

`sum of array elements is 27`

## Approach 2

In the second approach, we’ll use the inbuilt method `sum()`

to calculate the sum of elements of an array.

Please note that you can pass any `iterable`

to the sum() function.

sum = sum(arr) print("sum of array elements is ",sum)

Output

`sum of array elements is 27`
