The ultimate goal is to create a script thatâll draw the American flag (weâre learning this piece by piece in class. So, I need to create a function that will color in the star that I can call multiple times for each star. Any help is greatly appreciated!

Look at turtle.begin_fill and turtle.end_fill
That's after making sure your star is a closed shape.
