Description and Code walkthrough

The tic-tac-toe game is for two players. One player plays X and the other plays O. The players take turns placing their marks on a grid of three-by-three cells. If a given player gets three marks in a row horizontally, vertically, or diagonally, then that player wins the game. The game will be tied if no one gets three in a row by the time all the cells are marked.

1. When we select to play with a desktop a random selection is made by the computer using the random module in Python - https://www.geeksforgeeks.org/python-random-module/

import random 

2. Next thing we need to import is the subprocess module - Subprocess in Python is used to run new programs and scripts by spawning new processes. And it enables the user to launch new programs right from the current Python program thanks to the subprocess module.

we have used the call method of subprocess - The Python subprocess call() function returns the executed code of the program. If there is no program output, the function will return the code that it executed successfully

import subprocess

subprocess.call(["python","main.py"])

3. Your goal with this project is to create a tic-tac-toe game in Python. For the game interface, you’ll use the Tkinter GUI tool kit https://docs.python.org/3/library/tkinter.html

from tkinter import *
import from tkinter import ttk

4. We have also used the time module in python - as name suggests it allows us to work with the time https://www.geeksforgeeks.org/python-time-module/

import time

5. So now we have all imports in place we can start with the logic to build tic-tac-toe. So first we need to make the structure of the game on the GUI how it will look basically we need a grid of 3x3 , this code is responsible for how the GUI is built -

def center_window(w=300, h=200):
    # get screen width and height
    ws = root.winfo_screenwidth()
    hs = root.winfo_screenheight()
    # calculate position x, y
    x = (ws/2) - (w/2)    
    y = (hs/3) - (h/3)
    root.geometry('%dx%d+%d+%d' % (w, h, x, y))

user=1
plyrs = 1
LARGE_FONT= ("Verdana", 12)
NORM_FONT = ("Helvetica", 10)
SMALL_FONT = ("Helvetica", 8)
bord = [0,0,0,0,0,0,0,0,0]
positions = [[80,100],[200,100],[320,100],[80,220],[200,220],[320,220],[80,340],[200,340],[320,340]]
root = Tk()
center_window(500,500)
root.title("Tic Tac Toe")

6. Now we need a function that determines the winning logic for the game, for that we need to decide how the winner is determined -

-Select the first turn of the player randomly. -Write an infinite loop that breaks when the game is over (either win or draw). -Show the board to the user to select the spot for the next move. -Ask the user to enter the row and column number. -Update the spot with the respective player sign. -Check whether the current player won the game or not. -If the current player won the game, then print a winning message and break the infinite loop. -Next, check whether the board is filled or not. -If the board is filled, then print the draw message and break the infinite loop. -Finally, show the user the final view of the board.

def winning_condition(user):
    for i in range(0,len(bord)):
        if((bord[0]==user and bord[1]==user and bord[2]==user) or (bord[0]==user and bord[3]==user and bord[6]==user) or (bord[2]==user and bord[5]==user and bord[8]==user)
            or (bord[6]==user and bord[7]==user and bord[8]==user) or (bord[3]==user and bord[4]==user and bord[5]==user) or (bord[1]==user and bord[4]==user and bord[7]==user)
            or (bord[0]==user and bord[4]==user and bord[8]==user) or (bord[2]==user and bord[4]==user and bord[6]==user)):
            winner_msg(user)
            Button(root,text="Exit",bg="#ff2e2e", width=8,font=("bold",20),fg="white",command="exit").place(x=270,y=240)
            Button(root,text="ReMatch",bg="#ff2e2e", width=8,font=("bold",20),fg="white",command=rematch).place(x=100,y=240)
            return 1
    return 0

    //this method shows the message of the result
    def winning_condition(user):
    for i in range(0,len(bord)):
        if((bord[0]==user and bord[1]==user and bord[2]==user) or (bord[0]==user and bord[3]==user and bord[6]==user) or (bord[2]==user and bord[5]==user and bord[8]==user)
            or (bord[6]==user and bord[7]==user and bord[8]==user) or (bord[3]==user and bord[4]==user and bord[5]==user) or (bord[1]==user and bord[4]==user and bord[7]==user)
            or (bord[0]==user and bord[4]==user and bord[8]==user) or (bord[2]==user and bord[4]==user and bord[6]==user)):
            winner_msg(user)
            Button(root,text="Exit",bg="#ff2e2e", width=8,font=("bold",20),fg="white",command="exit").place(x=270,y=240)
            Button(root,text="ReMatch",bg="#ff2e2e", width=8,font=("bold",20),fg="white",command=rematch).place(x=100,y=240)
            return 1
    return 0
