Create your own decorators in Python
Learn how to use decorators to augment your functions and classes.
💡
Why Learn Decorators?
Decorators are everywhere in Python. From Flask routes to to dataclasses — decorators pop up all over in Python.
Decorators use the @ syntax to augment the behavior of functions and classes. They rely on the fact that Python's functions are first-class objects that can be passed into other functions and dynamically defined within other functions.
