Section 17.3 Objects Revisited
In Python, every value is actually an object. Whether it be a turtle, a list, or even an integer, they are all objects. Programs manipulate those objects either by performing computation with them or by asking them to perform methods. To be more specific, we say that an object has a state and a collection of methods that it can perform. The state of an object represents those things that the object knows about itself. For example, as we have seen with turtle objects, each turtle has a state consisting of the turtle’s position, its color, its heading and so on. Each turtle also has the ability to go forward, backward, or turn right or left. Individual turtles are different in that even though they are all turtles, they differ in the specific values of the individual state attributes (maybe they are in a different location or have a different heading).
