I changed the building size, color, and my original project idea to something simple.

I got stuck on super turtle animuation. Everytime I try to open drawing.py it wouldn't open. Then, my instructor helped me by telling me to type poetry shell and it worked.
Additionally, I want to learn more about superturtle because i was a little confused about the codes.
