The @property decorator in Python is used to define methods that can be accessed like attributes. It allows us to create getters, setters, and deleters for class attributes, enabling us to control access to the attribute and add validation or computation logic. This tutorial covers the usage ...

Python programming provides us with a built-in@propertydecorator which makes usage of getters and setters much easier inObject-Oriented Programming. Before going into details on what@propertydecorator is, let us first build an intuition on why it would be needed in the first place. Class Without...
Python provides a built-in @property decorator which makes usage of getter and setters much easier in Object-Oriented Programming.Properties are useful because they allow us to handle both setting and getting values in a programmatic way but still allow attributes to be accessed as attributes....

However, the decorator approach is more popular in the Python community.Creating Attributes With property() You can create a property by calling property() with an appropriate set of arguments and assigning its return value to a class attribute. All the arguments to property() are optional. ...
