Python program to print check board pattern of n*n using numpy
Given the value of n, our task is to display the check board pattern for a n x n matrix.
Different types of functions to create arrays with initial value are available in numpy . NumPy is the fundamental package for scientific computing in Python.
Algorithm
Step 1: input order of the matrix. Step 2: create n*n matrix using zeros((n, n), dtype=int). Step 3: fill with 1 the alternate rows and columns using the slicing technique. Step 4: print the matrix.
Example Code
import numpy as np
def checkboardpattern(n):
print("Checkerboard pattern:")
x = np.zeros((n, n), dtype = int)
x[1::2, ::2] = 1
x[::2, 1::2] = 1
# print the pattern
for i in range(n):
for j in range(n):
print(x[i][j], end =" ")
print()
# Driver code
n = int(input("Enter value of n ::>"))
checkboardpattern(n)
Output
Enter value of n ::>4 Checkerboard pattern: 0 1 0 1 1 0 1 0 0 1 0 1 1 0 1 0
