In this program, you will learn how to find the sum of even elements of an array in Python.

`a = arr.array('i', [10, 20, 30, 40])`

## Example: How to find the sum of even elements of an array in Python

```
import array as arr
a = arr.array('i', [])
s = 0
k = int(input("Enter size of array:"))
for i in range(0, k):
num = int(input("Enter %d array element:" % (i + 1)))
a.append(num)
for i in a:
if i % 2 == 0:
s = s + i
print("Sum of even elements:", s)
```

#### Output:

```
Enter size of array:4
Enter 1 array element:2
Enter 2 array element:3
Enter 3 array element:4
Enter 4 array element:5
Sum of even elements: 6
```
