A simple and practical decorator for Python

The Python call function can provide a value that Key=value represents this parameter, and we can call the function without the order of the function definition .... (*A,**B) can be used as an adorner to provide indeterminate parameters ... Greatly reducing the coupling of the adorner and the decorated function def func (): Return 1///Returns the name of the function func.__name__//////the static method of implementing the class with the Adorner class class: @st Aticmethod def OK (): print "OK" class.ok ()/////indeterminate parameter adorner #encoding =utf-8def Deco (func): Def _infunc (*args,**kva        RGS): Print ("before MyFunc () called.")
