I need to do the following. However, I am struggling with finishing the requested coding. This is from Python 3.7.

Specific tasks are to:

1. Improve the code by using the for loop.
2. Change the Target to be a Rectangle
3. Change the arrow to the Ball
4. Make the ball size decreasing when it gets closer to the Target
5. Add two lights: red and green changing colors after the ball hits the Target

scene = Canvas() scene.setBackgroundColor('skyBlue') grass = Rectangle(200, 80, Point(100,160)) grass.setFillColor('green') grass.setBorderColor('green') grass.setDepth(100) scene.add(grass) sun = Circle(20, Point(50,30)) sun.setFillColor('yellow') scene.add(sun)

target = Layer() outside = Rectangle(50, 70) outside.setFillColor('white') outside.setDepth(49) target.add(outside) middle = Rectangle(30, 50) middle.setFillColor('blue') middle.setDepth(48) target.add(middle) inside = Rectangle(20, 30) inside.setFillColor('red') inside.setDepth(47) target.add(inside) legs = Path(Point(-25,45), Point(0,0), Point(25,45)) legs.setBorderWidth(2) target.add(legs) target.move(160,110) target.setDepth(75) # in front of grass; behind arrows scene.add(target)

# prepare three arrows, but do not yet add to scene arrow1 = Circle(5) arrow1.setFillColor('purple')

arrow1.move(15,120) # initial position arrow2 = arrow1.clone() arrow3 = arrow1.clone()

dialogue = Text('Click target to fire an arrow') dialogue.move(100,170) scene.add(dialogue)

scene.wait() # wait for user event anywhere on canvas scene.close()
