Nested while-s

[Harald Hanche-Olsen]

| Is it not possible to nest while's?

It sure is.

| Consider this code:
| 
| def listOfRadius(radius, xpos, ypos):
| 	list = []
| 	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
| 
| It will list only the values from the nested while.

Move the initialization of currentY into the top of the outer while
loop.
