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

`a = arr.array('i', [2, 3, 4, 5])`

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

```
import array as arr
a = arr.array('i', [])
se = sod = 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:
se = se + i
else:
sod = sod + i
print("Sum of even elements:", se)
print("Sum of odd elements:", sod)
```

#### 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
Sum of odd elements: 8
```
