^^^^^^^^My code so far^^^^^^^^^^^^

write in python

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. Improve the code by using the for loop.

5. Make the ball size decreasing when it gets closer to the Target

Add two lights: red and green changing colors after the ball hits the Target
