Tkinter guide?

That is not a good way to make a full screen window. A better way is to use .attribute()

window.attributes('-fullscreen',True)

Or if you want to use geometry, use "winfo_screenwidth" and "winfo_screenheight" to get the screen dimensions.

width= window.winfo_screenwidth() 
height= window.winfo_screenheight()
window.geometry(f'{width}x{height}')

The problem with hardcoding a number is it will not work on different resolution monitors.
