## Example: How to find the sum of array elements 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:
s = s + i
print("Sum of array elements:", s)
```

#### Output:

Enter size of array:4
Enter 1 array element:10
Enter 2 array element:20
Enter 3 array element:30
Enter 4 array element:40
