PYTHON PROGRAMING : Code must only be in python. A tic-tac-toe grid of size n is a grid composed of empty tiles bounded by solid lines. The grid is composed of n tiles in width and n tiles in height. Tic-tac-toe is usually played on a grid of size 3. We want to write a program to display on the console a tic-tac-toe grid of size n. Each tile has a certain width in number of characters (for example 6) and a certain height in number of lines (for example 3). Here is the expected output of the program for n = 3: # # # # # ##################### # # # # # ##################### # # # # # # You need to display a tic-tac-toe grid of size n = 3 that respects this exact display format, with tiles of size 6 x 3. It should be easy to modify your program to change n, the width and height of…
