Print checkerboard pattern of nxn using numpy

A checkerboard pattern alternates between two colors (or values), traditionally black (or 1) and white (or 0). Let's see how to create an nxn checkerboard pattern using NumPy.

Tutorial: Creating an nxn Checkerboard Pattern with NumPy

  1. Initialization

    Start by importing NumPy:

    import numpy as np

  2. Creating the Checkerboard Pattern

    A simple method to create a checkerboard pattern is to utilize integer division and the modulo operation. For any cell (i, j) in an nxn matrix, the cell should be 1 if (i+j) % 2 is 1, and 0 otherwise.

    def checkerboard(n):
    return np.fromfunction(lambda i, j: (i + j) % 2, (n, n), dtype=int)

    In the above function:

    • np.fromfunction constructs an array by executing a function over each coordinate.
    • The lambda function (i, j): (i + j) % 2 returns 1 for odd sums of coordinates and 0 for even sums, which is the essence of the checkerboard pattern.

  3. Using the Function

    Now, you can create an nxn checkerboard by calling the function with your desired size:

    n = 8  # Example for an 8x8 checkerboard
print(checkerboard(n))

    The output will be:

    [[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]]

    As you can see, the checkerboard pattern has been printed successfully.

This approach leverages NumPy's capability to efficiently handle array operations, making it suitable for creating large checkerboard patterns.

1. Print checkerboard pattern in Python with NumPy:

Printing a checkerboard pattern involves creating a matrix with alternating 0s and 1s using NumPy.

import numpy as np

# Define the size of the checkerboard (n x n)
n = 8

# Create a checkerboard pattern using NumPy
checkerboard = np.zeros((n, n), dtype=int)
checkerboard[1::2, ::2] = 1
checkerboard[::2, 1::2] = 1

# Print the checkerboard pattern
print("Checkerboard Pattern:")
print(checkerboard)

2. Creating checkerboard pattern of nxn using NumPy:

Generate a checkerboard pattern of size nxn using NumPy.

import numpy as np

# Create a checkerboard pattern using NumPy
checkerboard = np.zeros((n, n), dtype=int)
checkerboard[1::2, ::2] = 1
checkerboard[::2, 1::2] = 1

# Print the checkerboard pattern
print("Checkerboard Pattern:")
print(checkerboard)

3. NumPy code for printing checkerboard pattern:
