How to make a checkerboard in numpy?

Question

I\'m using numpy to initialize a pixel array to a gray checkerboard (the classic representation for \"no pixels\", or transparent). It seems like there ought to be a whizzy

Answer 1

Simplest implementation of the same.

import numpy as np

n = int(input())
checkerboard = np.tile(np.array([[0,1],[1,0]]), (n//2, n//2))
print(checkerboard)
