Decorators in Python are a powerful and flexible way to modify or extend the behavior of functions or methods. They allow you to wrap a function with additional functionality. In this tutorial, we'll explore how to create a custom decorator with arguments in Python.
In Python, a decorator is a function that takes another function as input and extends the behavior of the latter function without explicitly modifying its code. Decorators are often used for tasks such as logging, timing, authentication, and more.
Let's start by creating a simple decorator without any arguments.
In this example, simple_decorator is a basic decorator that adds some behavior before and after the execution of the decorated function. The @simple_decorator syntax is a shorthand for my_function = simple_decorator(my_function).
Now, let's enhance our decorator to accept arguments.
In this example, decorator_with_arguments is a decorator factory that takes arguments arg1 and arg2. It returns the actual decorator real_decorator, which then wraps the target function with the provided arguments.
You can also apply multiple decorators to a single function.
