Controlling the order of drawing objects

Question

It appears that in Python graphics.py, new objects are drawn behind existing objects. So if I draw a blue circle and THEN place a rectangular box over half the circle, you find the circle in on top of the rectangular box. The box, even though it was written last, is appearing behind the circle. Is there a way to control this behavior so the rectangle would appear on top of the circle and not behind it? I want to avoid having to undraw the circle, draw the rectangle, then redraw the circle, so that the rectangle is on top of the circle instead of behind it.

Certainly, this becomes more cumbersome as you have more and more overlapped objects.
