The Basics of Property Decorators

In Python, the property decorator (@ property) is used to create getter methods, allowing you to define properties in a class. This means you can access your class attributes like they were public attributes while actually controlling access through methods. The complete form includes a definition, getter, setter, and deleter, as shown in the example below:

In this setup:

@ property creates the property.

The Role of @ property

The @ property decorator is essential as it defines the property itself. Without starting with @ property, you will encounter an error. For example, if you try to define just the getter like this:

You will get an error message saying that name is not defined.

Example of Getter Redefinition

Consider the following example, where we redefine the getter:

When to Use Which Decorator

Use @ property when you define a new property.

This initializes the property and its first getter method.

This allows you to change the behavior of the existing property without altering its definition.
