I’m trying to create a minesweeper game and I need to be able to pick out a single square.

from tkinter import *
import random

startX = 0
startY = 0

game = Tk()

game.geometry('600x600')
game.title('Simon')
canvas = Canvas(game, width=600, height=600, bg='#13cce7')

canvas.pack()

for j in range(4):
    for i in range(4):
        tile = canvas.create_polygon(startX, startY, startX+150, startY, startX+150, startY+150, startX, startY+150, fill="grey", outline="black", width="5")
        startY = startY+150
    startY = 0
    startX = startX+150
