            Understanding Python Decorators
            
+        
            Python decorators are a powerful feature that allows you to modify the behavior of functions or classes. They use the @syntax and are commonly used for logging, authentication, and caching.
            
+        
            A decorator is essentially a function that takes another function as an argument and returns a new function that usually extends the behavior of the original function.
