How to set turns playing tictactoe?

[Mariano]

I don't know how to set turns: human Vs computer. Based on my code: the computer's movement needs the human to click on any button.

from tkinter import *
import random

root = Tk()
root.title("Tres en raya")
root.resizable(0, 0)

board = [' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ']


def lucky_guess():
    movement = random.randint(0, 8)
    while board[movement] == 'X' or board[movement] == 'O':
        movement = random.randint(0, 8)
    print("The computer has chosen the tile number: ", movement)
    board[movement] = "O"
    if movement == 0:
        tile_0["text"] = "O"
    elif movement == 1:
        tile_1["text"] = "O"
    elif movement == 2:
        tile_2["text"] = "O"
    elif movement == 3:
        tile_3["text"] = "O"
    elif movement == 4:
        tile_4["text"] = "O"
    elif movement == 5:
        tile_5["text"] = "O"
    elif movement == 6:
        tile_6["text"] = "O"
    elif movement == 7:
        tile_7["text"] = "O"
    elif movement == 8:
        tile_8["text"] = "O"
