I don’t understand why Tkinter doesn’t show up. I run it but Tkinter doesn’t show up and this is my game code :

import tkinter 
import random
gameOver = False
score = 0
squaresToClear = 0
def play_bombdodger():
    create_bombfield(bombfield)
    window = tkinter.TK()
    layout_window(window)
    window.mainloop()
bombfield = []
def create_bombfield(bombfield):
    global squaresToClear
    for row in range(0,10):
        rowList = []
        for column in range(0,10):
            if random.randint(1,100) < 20:
               rowList.append(1)
            else:
                rowList.append(0)
                squaresToClear = squaresToClear + 1
        bombfield.append(rowList)
    printfield(bombfield)
def printfield(bombfield):
     for rowList in bombfield:
         print(rowList)
play_bombdodger
def layout_window(window):
    for rowNumber, rowList in enumerate(bombfield):
        for columnNumber, columnEntry in enumerate(rowList):
            if random.randint(1,1000) < 25:
                square = tkinter.Label(window, text = "    ", bg = "darkgreen")
            elif random.randint(1,1000) > 75:
                square = tkinter.Label(window, text = "    ", bg = "seagreen")
            else:
                square = tkinter.Label(window, text = "    ", bg = "green")
            square.grid(row = rowNumber,column = columnNumber)
play_bombdodger

I went on the internet to look it up and expected it to be successful but I was completely disappointed
