Decorators in Python

In Python, decorators are a powerful and flexible way to modify or enhance the behavior of functions or methods without changing their code. Decorators are essentially functions themselves, and they are used to wrap other functions or methods to extend or modify their functionality.

In this example, the my_decorator function is used as a decorator for the greet function. When you call greet("Alice"), it actually calls the wrapper_function defined inside my_decorator, which adds behavior before and after the original greet function is called.

Getters and Setter

In Python, getters and setters are methods used to control access to class attributes or instance variables. They are a part of the concept of encapsulation, which helps in maintaining data integrity and controlling how data is accessed and modified. Getters are used to retrieve the value of an attribute, and setters are used to modify the value of an attribute while applying some validation or logic.

Note: Using the setter method, we can conditionally set the value of our data members.
