Using python do the following

Without storing the moves we can't check to avoid drawing in the same cell. We'll use a list in which the items are themselves lists representing a row of the TiTacToe grid. Write the functions initialise_record_of_moves and is_occupied. The former uses the grid (a tuple) to create the list representing the cells in the grid where the strings "X" and "O" can be stored as moves are played. All of the cells (items in the list) should be initialised to " " (a space). The is_occupied function has parameters moves_played (the list representation of the grid of cells) and cell (a pair tuple with row and column) and returns true if the specified cell already has an X or O drawn in it. Your functions must satisfy the test cases in the test harness provided below, and you should add a few more test cases for the is-occupied function.

the test suite is as follows:

#

# Obtain code for turtle graphics

#

import turtle, sys

def is_occupied(moves_played, cell):

''' return True if the cell, a tuple (c,r), is already occupied by a move;

otherwsie return False '''

def initialise_record_of_moves(grid):

''' return a 2-D list of size determined by the rows and columns of grid

initialised with string values = " " '''
