A little bit of Python's understanding of adorners

More and more, for some terms, really can not see the name of the idea to use their own language/ideas to try to explain, such as socket/sockets, and then such as adorners, only by literal meaning, difficult to understand, but will take you to the pit

def F1 (FN):     def action ():         return " <a> "+fn () +"</a>"    return  action@f1  def  Test ():    return"istest"print Test ()

Run results

<a> is test</a>

In an example

defF1 (FN):defaction ():return "<a>"+FN () +"</a>"    returnActiondefTest ():return "is test"PrintF1 (Test) ()#Attention!!! The adorner is gone, and the output of the end is changed.

In this way, the adorner is so much more understandable.

# actually @f1 def Test ():     Pass # here is equivalent to:test=f1 (Test)
