* save the result of this into a global variable (that is, it should be a variable defined outside of all of your functions) * create a function called draw_sky: * within it, iterate through the global list you created * draw a star based on the data in the sub list (x, y and size) * call you draw_sky function once... * it should look something like this: ![lots of stars]( - 008/resources/img/turtle/starry_4.png) Extra Credit ----- 5 points * within your draw sky function, increment the x value of every sub list by 1 as you iterate through the sub lists to draw stars * instead of calling your draw_sky function once, use ontimer to have you draw_sky function call itself again in 30 ms * call ontimer at the end of your draw_sky function * with draw_sky as the first argument (no quotes), and 30 as the second * you should see an animation! * now... change your generate_star_data function so that the sub list that creates also contains a 4th value * this value represents a velocity * it should be small (maybe between 1 and 5) * in your draw_sky function, as you iterate through your list of star data, add the generated velocity (the value at index 3) to the x value (the value at index 0) rather than just increment by 1 ![animation]( - 008/resources/img/turtle/starry_ec.gif)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
