Taylor feels relieved that Turtleâs first sound was a laugh; it reassures Taylor that she is doing a decent job of raising Turtle, for she feels that if Turtle were unhappy, she would not laugh. A little later, as Turtle and Taylor help Mattie plant the garden, Turtle says her first word: âbean.â. One night, Lou Ann tells Taylor about her fear that the horrible things she imagines will happen in real life. She tells Taylor that in high school she stood looking over a cliff and imagined jumping.
Our first turtle program Â¶. Letâs write a couple of lines of Python program to create a new turtle and start drawing a rectangle. (Weâll call the variable that refers to our first turtle. , but we can choose another name if we follow the naming rules from the previous chapter).he one weâll look at in this chapter allows us to create turtles and get them to draw shapes and patterns. The turtles are fun, but the real purpose of the chapter is to teach ourselves a little more Python, and to develop our theme of computational thinking, or thinking like a computer scientist.
