hi,
im currently making a food ordering system in python. I recently decided to put a background in the window and now all of my buttons have disappeared?? does anyone know why this might be.

N=p(2);
sum = 0;
for i = 1:N
sum = sum+ ((x(i+1) - x(i))^2+(y(i+1)-y(i))^2)^.5;
end ChargrO
i'm kinda new to this so could you possibly dumb it down for me?

Well, it doesn't even look like deepak's code is Python. I'm not quite sure what is going on with that.
Anyways, I do not see any immediate problems why your code should not work except for the constant calling of the function "create_top." You call it eight times? That would mean you create eight canvases with eight background images? Am I missing something or is that your most apparent problem?
EDIT: If this is actually tyonyjv's code, I will definitely not try to question its methods; his GUI algorithms are above my skill level. He will unquestionably know more about it than I do, so try to ask him politely. Good luck.

That is not your code. That is code I wrote for a base of checkers program in earlier thread, including comments and diag_stripe routine for producing the board. Remember to mention the origin of your code or at least not claim that you wrote it.

You mixed up the order of frames:
def create_top(frame):
top = Canvas(frame, bg='white', width=s, height=s)
# pick a .gif image file you have in the working directory
# creates the background
image1 = tk.PhotoImage(file="foodimage.gif")
w = image1.width()
h = image1.height()
panel1 = tk.Label(top, image=image1) ## top!!!
panel1.pack(side='top', fill='both', expand='yes')
panel1.image = image1
return top

I would not put Help but exchange it with Order Food.
