Hi Steven, I'm not sure what you are asking help for. Do you want help to draw the diamond or how to nest for loops? In plain language, what is your end goal after it's all written?

Assuming that you are asking for help drawing a diamond shape, I can tell you that I would not be using a for loop at all. That is to say that you are able to draw lines. If drawing only pixels is your problem's limitation then, yes a for loop would be needed, but not if you have other basic graphical shape functions.

I won't get into how I'd draw the diamond just yet, as I don't know what limitations and context you're working under, but if you come back and explain your problem and what rules you are working under then I'd be happy to assist you where I can.
