2. Using Python, write a function trafficLight() to do the
following. First, it will draw a simple traffic light in a graphics
window that is 200 pixels
wide by 200 pixels high. The three lights should have a diameter of
50 pixels each, and the traffic light should be centered in the
graphics window. Second, the next mouse click in the window
makes the green light green and the other two gray, the click after
that makes the yellow light yellow and the other two gray, the
click after that makes the red light red and the other two gray.
The next mouse click should go back to
green and as long as you keep clicking the light will
cycle.
*you might want if __name__ == "__main__": trafficLight() so you can watch it run
