I had to think about the function of brackets, and I learned that the items inside of the brackets makes a list. Listing multiple items with commas does not create what we are trying to draw, we need to add 'for-loop' and the language 'for size in sizes' was not understood intuitively. I am unsure if I fully understand all of this yet, but manage to mimick the process.
