Why was floor division used here?

512 / 8 = 64

Is this a good practice or something? Thank you in advance.

Please don't post your Python code as an image file. Read this help topic to learn how to format your code in this forum.

WIDTH = HEIGHT = 512
DIMENSION = 8
SQ_SIZE = HEIGHT // DIMENSION

Floor division is used here because it returns an integer (int type) instead of a floating number (float type). We want SQ_SIZE to be an integer.

>>> 512 / 8
64.0
>>> 512 // 8
64

To get a neat fit!

# start with an approximate size
approx_chess_board_side = 529
num_squares_per_side = 8
individual_square_size = approx_chess_board_side // num_squares_per_side
print(f'Make the chess board sides {8 * individual_square_size}, then everything fits neatly.')

Why not start with the individual squares?

# start with the individual squares 
units = 'inche(s)'
one_square_side = 2
chess_board_side = 8 * one_square_side
frame_width = 1
print(f'The chess board will be {chess_board_side} x {chess_board_side} {units} square, with a frame of  {frame_width} {units} around it.')
print('All inlaid with gold filaments and finest blue-green and mutton-fat-white jade from 新疆和田!')
