In Python
@A
@B
def func:

would become func=A( ) (B ( ) (func) )

So the following definitions

@request("GET", "*/integer")
    @response("%d")
    def portRead(self):
        return self.__portRead__()

 def __portRead__(self):
        raise NotImplementedError

would become request("GET", "*/integer") (response("%d") (portRead())

My question
1)is request() and response () functions? I couldn't find their function definition anywhere.
To me, seem like they are more like Http REST calls rather function. How would that relate to the template decorator function I listed above?

2)_portRead_ is nothing there except raise exception. Is that right?

Out of context your code will not work, apart from the indentation you will get 'request' is not defined. The chances are there was an import further up with a module that contained the definitions of the decorator objects (so for your q1, they only have to be 'callable', they could be defined as classes with a __call__ method).

Those decorator objects will contain code that does something using the arguments passed to them and inserts the portRead function code somewhere inside them. Like this
