I created a game and there is this part of the code I don't understand.tk.wm_attributes("-topmost", 1)
What does the number after "-topmost" mean? I changed the number to 0 and 255, yet there is no difference. Why is that?

I also checked the tkinter documentation and I can't find the function.
The topmost attribute requires a value that can be converted to True or False in the tcl language. 1 or any other number greater than zero evaluates to True. 0 will evaluate to False.
So, tk.wm_attributes("-topmost", 1) sets the topmost option on, and a value of 0 turns it off.
What does the one in 'tk.wm_attributes("-topmost", 1) mean?
