Sure!

> 	currentX = (xpos - radius)
> 	currentY = (ypos - radius)
> 	while currentX <= (xpos + radius):
> 	    while currentY <= (ypos + radius):
> 		    str1 = `currentX` + " , " + `currentY`
> 		    list.append(str1)
> 		    currentY = currentY + 1
> 	    currentX = currentX + 1
> 	return list

Note that you never reset currentY to ypos-radius, so the inner loop won't
be entered on any but the first iteration of the outer loop.  You probably
want to change

    currentY = (ypos - radius)
    while currentX <= (xpos + radius):

to

    while currentX <= (xpos + radius):
        currentY = (ypos - radius)

(that is, just swap those two lines).
