Tic-Tac-Toe

[juliabrushett]

Hello!

I am trying to make a Tic-Tac-Toe game, and I am having trouble with the 'X' and 'O' characters showing up in my program. My code is below:

from tkinter import *

grid = [[0 for i in range(3)] for j in range(3)]
numClicks = 0
isDone = False
isXTurn = True

def restart() :
    print("Restart Game")

def resetGame() :
    global isXTurn
    global isDone
    global numClicks
    for i in range(3) :
        for j in range(3) :
            grid[rw][col].config(text = " ")

def markSpace(rw, col) :
    global isXTurn
    global isDone
    global numClicks

    numClicks = 0
    isXTurn = True
    isDone = False

    space = grid[rw][col].cget("text")
    if(isDone == True) :
        return
    elif (space == " ") :
        if (space == isXTurn) :
            grid[rw][col].config(text = "X", fg = "red")
            lblStatus.config(text = "O\'s Turn")
        else :
            grid[rw][col].config(text = "O", fg = "blue")
            lblStatus.config(text = "X\'s Turn")
    else :
        lblStatus.config(text = "Invalid Move")
        return

def gameOver(rw, col) :
    global numClicks
    global isDone
    winner = ' '

    if(grid[0][0].cget('text')  == grid[1][1].cget('text') and grid[1][1].cget('text') == grid[2][2].cget('text')) :
        winner = grid[0][0].cget('text')
    elif(grid[2][0].cget('text')  == grid[1][1].cget('text') and grid[1][1].cget('text') == grid[0][2].cget('text')) :
        winner = grid[2][1].cget('text')

    else :
        for r in range(0, 3) :
            if(grid[r][0].cget('text') != ' ' and grid[r][0].cget('text') == grid[r][1].cget('text') and grid[r][1].cget('text') == grid[r][2].cget('text')):
                winner = grid[r][0].cget('text')
            elif(grid[0][r].cget('text') != ' ' and grid[0][r].cget('text') == grid[1][r].cget('text') and grid[1][r].cget('text') == grid[2][r].cget('text')):
                winner = grid[0][r].cget('text')

    isDone = True
    if(winner == ' ' and numClicks >= 9) :
       lblStatus.config(text = 'Tie Game')
    elif(winner != ' ') :
        lblStatus.config(text = winner + ' Wins!')
    else :
        lblStatus.config(text = 'X\'s Turn' if isXTurn else 'O\'s Turn')
        isDone = False

main = Tk()
main.title("Tic-Tac-Toe")
main.geometry("355x420")

topFrame = Frame(main, width = 320, height = 40)
topFrame.place(x = 12, y = 12)

lablStatus = Label(topFrame, text = "O's Turn")
lablStatus.config(fg = "blue", bg = "yellow", font = "serif 16 bold")
lablStatus.pack(side = TOP)

mainFrame = Frame(main, width = 330, height = 330)
mainFrame.config(bg = "black")
mainFrame.place(x = 10, y = 42)

for rw in range(0, 3) :
    for col in range(0, 3) :
        grid[rw][col] =  Button(mainFrame, text=" ", relief = 'solid' )
        grid[rw][col].config(font = "monospace 36 bold", fg = 'red', height = 1,  width = 3)
        grid[rw][col].place(x = rw*105 + 10, y=col*105+10)

btnRestart = Button(main, text = "Restart", command = resetGame, width = 30)
btnRestart.place(x = 45, y = 380)


main.mainloop()

small change in code: lines 24-26 are now

 numClicks += 1
 isXTurn = not isXTurn
 gameOver(rw, col)
