Attributes, Methods, and self
Explore how to add behavior to Python objects by defining instance methods that manage attributes through the self parameter. Understand how methods encapsulate logic to safely modify an object's state and how complex behaviors can be built by calling methods within a class. This lesson helps you learn how to create self-contained, functional objects in Python.
We'll cover the following...
Our Spaceship objects currently contain attributes but no behavior. They store attributes such as fuel level and shield strength, but do not yet define any actions. At this stage, they function only as data containers. Behavior must be added to make the objects functional. This lesson introduces instance methods that allow a spaceship to launch, consume fuel, and manage system state. This demonstrates how combining data and logic within a class enables each object to manage its own state.
Defining behavior with methods
An instance method is a function defined inside a class that operates on an object's data. Attributes represent state (for example, a fuel level of 100 units), while methods represent behavior (for example, reducing fuel by 10 units during ...
