Until now, we've had to write out numbers every time we want Tina to move. We can use a list of numbers and a loop to get her to move many times! ```python.run import turtle tina = turtle.Turtle() tina.shape('turtle') number_list = [1,2,3,4,5,6,7,8,9,10] tina.color("green") for number in number_list: tina.forward(number*10) tina.left(60) ``` The code `number_list = [1,2,3,4,5,6,7,8,9,10]` is where Tina gets her numbers from. Can you change the numbers in the list to change how she moves? Make sure that your list starts and ends with square brackets (`[]`), and has a comma (`,`) in between every number.
