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
