A turtle can be commanded to crawl over a sheet of paper with a pen tied to its tail. The turtle module in Python allows you to control a turtle shape to draw on a graphic window. Basic turtle commands include moving the turtle forward or turning it right by a set number of degrees. Challenges for using the turtle include drawing shapes like squares and hexagons of varying sides, as well as getting the turtle to draw a person's initials.
