Answer to Question #101283 in Python for gina franco

Question

can you please help me help my son with this assignment . he is new to this and we are so stuck

In this assignment, you will use all of the graphics commands you have learned to create an animated scene. Your program should have a clear theme and tell a story. You may pick any school-appropriate theme that you like.

The program must include a minimum of:

5 circles
5 polygons
5 line commands
2 for loops
1 global variable
You may wish to use the standard boilerplate code for simplegui graphics
