Element-wise Sum

Calculate element-wise sum of two arrays.

1# Take arrays
2n = int(input("Enter array size: "))
3arr1 = []
4for i in range(n):
5    arr1.append(int(input(f"Array1 element {i+1}: ")))
6

7arr2 = []
8for i in range(n):
9    arr2.append(int(input(f"Array2 element {i+1}: ")))

11# Element-wise sum
12sum_arr = []
13for i in range(n):
14    sum_arr.append(arr1[i] + arr2[i])
15

16print(f"Sum array: {sum_arr}")

Output

Enter array size: 3
Array1 element 1: 1
Array1 element 2: 2
Array1 element 3: 3
Array2 element 1: 4
Array2 element 2: 5
Array2 element 3: 6
Sum array: [5, 7, 9]

What's going on

Add corresponding elements.

Key Concepts:

Arrays must be same size
Add arr1[i] + arr2[i]
Create new array
