Decorators are very useful feature in python programming for adding a new functionality to a existing Code or extend the behavior of the latter function without modifying the exisiting code.
Decorators in Python are functions that modify the behavior of other functions or methods, allowing for code reuse, adding functionality, and enhancing readability by enabling a clean separation of concerns. They are prefixed with @ symbol and are commonly used in web frameworks, like Flask and Django, for tasks such as authentication, logging, and caching.
Decorators in Python are a design pattern that allows you to add new functionality to an existing function without changing the original code. They operate by accepting a function as an argument, wrapping it with another function that extends its functionality, and returning the wrapped function. This is accomplished by placing the "@" symbol, followed by the decorator's name, before the function definition. Decorators are often used for logging, calculating execution time, resolving errors, and implementing authentication.
