def switchupdown(x=0, y=0): if pen()["pendown"]: end_fill() up() else: down() begin_fill()

def changecolor(x=0, y=0): global colors colors = colors[1:]+colors[:1] color(colors[0])

def main(): global colors shape("circle") resizemode("user") shapesize(.5) width(3) colors=["red", "green", "blue", "yellow"] color(colors[0]) switchupdown() onscreenclick(goto,1) onscreenclick(changecolor,2) onscreenclick(switchupdown,3) return "EVENTLOOP"

if __name__ == "__main__": msg = main() print(msg) mainloop()
