As mentioned earlier, A Python decorator is a function that takes in a function and returns it by adding some functionality. In fact, any object which implements the special__call__()method is termed callable. So, in the most basic sense, a decorator is a callable that returns a callable...
Python functions can also be used as an input parameter to the function. Syntax: defdecorator_name(function_name):defwrapper_function():...returnwrapper_function@decorator_namedeffunction_name(): Examples of Decorator in Python Following are the examples of decorator in python: Example #1 Code: ...

Decorators are a powerful feature in Python that allows you to modify or extend the behavior of functions or classes without changing their actual code. Decorators are widely used for logging, access control, instrumentation, and more. This tutorial will focus on understanding function decorators and...
Python decorators.py def do_twice(func): def wrapper_do_twice(): func() func() return wrapper_do_twice The do_twice() decorator calls the decorated function twice. You’ll soon see the effect of this in several examples.Note: You can name your inner function whatever you want, and ...

Learn Python decorators with hands-on examples. Understand closures, function and class-based decorators, and how to write reusable, elegant code.
http://wiki.python.org/moin/PythonDecoratorLibrary More examples of decorators. Note the number of these examples that use classes rather than functions as decorators. http://scratch.tplus1.com/decoratortalk Matt Wilson’s Decorators Are Fun. http://loveandtheft.org/2008/09/22/python-decorators...
These examples provide a foundational understanding of Python decorators and their various uses. By mastering decorators, you can write cleaner, more maintainable, and expressive code, enhancing the functionality of your functions in a modular and reusable way....
This is possible because everything in Python is a first-class object; thus, we can pass every Python construct as a parameter or assign it to a variable. That means every class, function, and declared variable could be passed as objects. The below examples demonstrate this: Code: def ...
