# Python Program to find sum of array

Given an array of integers, find sum of its elements.

Examples :

```Input : arr[] = {1, 2, 3}
Output : 6
1 + 2 + 3 = 6

Input : arr[] = {15, 12, 13, 10}
Output : 50
```
`Method 1:`

 `# Python 3 code to find sum  ` `# of elements in given array ` `def` `_sum(arr,n): ` `     `  `    ``# return sum using sum  ` `    ``# inbuilt sum() function ` `    ``return``(``sum``(arr)) ` ` `  `# driver function ` `arr``=``[] ` `# input values to list ` `arr ``=` `[``12``, ``3``, ``4``, ``15``] ` ` `  `# calculating length of array ` `n ``=` `len``(arr) ` ` `  `ans ``=` `_sum(arr,n) ` ` `  `# display sum ` `print` `(``'Sum of the array is '``, ans) ` ` `  `# This code is contributed by Himanshu Ranjan `

Output:

```Sum of the array is  34
```
`Method 2:`

 `# Python 3 code to find sum  ` `# of elements in given array ` `# driver function ` `arr ``=` `[] ` ` `  `# input values to list ` `arr ``=` `[``12``, ``3``, ``4``, ``15``] ` ` `  `# sum() is an inbuilt function in python that adds  ` `# all the elements in list,set and tuples and returns ` `# the value  ` `ans ``=` `sum``(arr) ` ` `  `# display sum ` `print` `(``'Sum of the array is '``,ans) ` ` `  `# This code is contributed by Dhananjay Patil  `

Output:

```Sum of the array is  34
```
