I drew code to get the shape of my skyscraper.

I got stuck on opening the drawing.py file.
I figured out later that i can't open because the file in empty so I used code . to code VS to writr the code.
I'm wondering if I can change my project a little from what I wrote in READ.MD.
I want to learn more about how to draw a shape inside a shape in turtle.
For future projects, I want to draw a figure sleeping.
