In this chapter, we’ll write short, simple programs to create beautifully complex visuals. To do this, we’ll use turtle graphics. In turtle graphics, you write instructions that tell a virtual, or imaginary, turtle to move around the screen. The turtle carries a pen, and you can instruct the turtle to use its pen to draw lines wherever it goes. By writing code to move the turtle around in cool patterns, you can make it draw amazing pictures.
Using turtle graphics, not only can you create impressive visuals with a few lines of code, but you can also follow along with the turtle and see how each line of code affects its movement. This will help you understand the logic of your code.
