The ultimate goal is to create a script that’ll draw the American flag (we’re 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.
