tkinter.TclError: bad geometry specifier (bug?)

Python Help
1

I’ve been searching forums for over an hr and can’t find anything. I’m following a tutorial for a snake game and I keep getting the bad geometry error. No spaces between numbers, im using x, not *, it’s lowercase… it’s driving me crazy!


from tkinter import *
import random

GAME_WIDTH = 700
GAME_HEIGHT = 700
SPEED = 50
SPACE_SIZE = 50
BODY_PARTS = 3
SNAKE_COLOR = "#00FF00"
FOOD_COLOR = "#FF0000"
BACKGROUND_COLOR = "#000000"


window = Tk()
window.title("Snake game")
window.resizable(False, False)

score = 0
direction = 'down'

label = Label(window, text="Score:{}".format(score), font=('consolas', 40))
label.pack

canvas = Canvas(window, bg=BACKGROUND_COLOR, height=GAME_HEIGHT, width=GAME_WIDTH)
canvas.pack

window.update()

window_width = window.winfo_width()
window_height = window.winfo_height()
screen_width = window.winfo_screenwidth()
screen_height = window.winfo_screenheight()

x = int(screen_width/2) - (window_width/2)
y = int(screen_height/2) - (window_height/2)

window.geometry(f"{window_width}x{window_height}+{x}+{y}")

window.mainloop()

I’m getting this error message and I can’t find what I’m doing wrong

Traceback (most recent call last):

Decimals aren’t permitted. You’re intifying the screen dimensions, but not the window dimensions.

I’d write it this way:

x = (screen_width - window_width) // 2
y = (screen_height - window_height) // 2

but other methods would work too.

when i run the code with either varaint, it opens the game window for 0.1 seconds and then closes itself, what could be the problem? Also, even after writing as you said it still gives me the same error.
