Python program to print nxn checkerboard using numpy



Checkerboard pattern for n = 8:

It consists of n * n squares alternating 0 for white and 1 for black.

We can do the same using x = np.zeros ((n, n), dtype = int)

Using this function, we initialize 2-D a matrix with zeros at all indices using

# Python nXn print program
# checkerboard pattern using numpy

 

import numpy as np

 
# function for printing a checkerboard

def printcheckboard (n):

 

print ( "Checkerboard pattern:" )

# create * n matrix

  x = np.zeros ((n, n) , dtype = int )

# fill in 1 alternate rows and columns

x [ 1 :: 2 , :: 2 ] = 1

x [:: 2 , 1 :: 2 ] = 1

  

# print template

for i in range (n):

for j in range (n):

print (x [i] [j], end = "" ) 

  print ( ) 

 
# driver code

n = 8

printcheckboard (n)

Exit: 

 Checkerboard pattern: 0 1 0 1 0 1 0 1 1 0 1 0 1 0 1 0 0 1 0 1 0 1 0 1 1 0 1 0 1 0 1 0 0 1 0 1 0 1 0 1 1 0 1 0 1 0 1 0 0 1 0 1 0 1 0 1 1 0 1 0 1 0 1 0
