return a function. We will use the Python @ syntax to place the decorator at the definition of the function:@log def Now (): Print ' 2013-12-25 'Calling now() a function will not only run the now() function itself, but will also now() print a line of logs before running the function:>>> now () Call Now ():2013-12-25Put @log to now() the definition of the function, the equivalent of executing a statement:now = log (now)Since log() it is a decorator that returns a function, the original now()

points:1. By adopting a combination that is not inherited, the decorator pattern enables the ability to dynamically extend the functionality of the object at run time, and can extend multiple functions as needed. Avoids the "poor flexibility" and "multi-subclass derivation issues" that are associated with inheritanceThe 2.Decorator class behaves as an inheritance of is-a component on the interface, that is, the decorator class inherits the interfaces that the component class has. But in the imp

an instance Decorating mode: dynamically adding some additional responsibilities to an object (not a Class). In terms of adding functionality, decorative mode is more flexible than creating subclasses , because sometimes our requirement is to add features to an object rather than to an entire class, such as adding a pendant to a mobile phone, a screen sticker, and so on, a more flexible way, Embedding the phone (the adorner class) into another obje
