Decorators in python : example

[Humble]

#!/usr/bin/python

def fun(*args, **kwargs):

        def fun1(*args, **kwargs):
                for a in args:
                        print a+'wrap power'
                for items in kwargs.items():
                        print items
                return "True"

        def fun2 ( *args, **kwargs):
                print "I am innocent"
        return fun1

@fun
def funcham(*args, **kwargs):
        print "I dont have the power or I am wrapped"
        return "nopower"

funcham( "hiii", asas = 12)




Lets execute above code:

[root]$ python decor.py
hiiiwrap power
('asas', 12)
[root]$


so, funcham is decorated here..

In simple terms “decorator “ returns a function.. The line

@fun is not exactly the decorator rather its a decorator line. 

Let me know if you need a detailed explanation on this.
