# Python3.x Python Calculate Sum of Array Elements
[ Python3 Examples](#)
Define an integer array and calculate the sum of its elements.
**Implementation Requirements:**
Input : arr[] = {1, 2, 3}
Output : 6
Calculation: 1 + 2 + 3 = 6
## Example
# Define function, arr is the array, n is the array length, can be used as an optional parameter, not used here
def _sum(arr,n):
# Use the built-in sum function
return(sum(arr))
# Call the function
arr=[]
# Array elements
arr =[12,3,4,15]
# Calculate the length of the array
n =len(arr)
ans = _sum(arr,n)
# Output the result
print('Sum of array elements is',ans)
The output of the above example is:
Sum of array elements is 34
