多重装饰器，即多个装饰器修饰同一个对象【实际上并非完全如此，且看下文详解】

1.装饰器无参数：

>>> def first(func):
    print '%s() was post to first()'%func.func_name
    def _first(*args,**kw):
        print 'Call the function %s() in _first().'%func.func_name
        return func(*args,**kw)
    return _first

>>> def second(func):

    print '%s() was post to second()'%func.func_name

    def _second(*args,**kw):

        print 'Call the function %s() in _second().'%func.func_name

        return func(*args,**kw)

    return _second

>>> @first

@second

def test():return 'hello world'

test() was post to second()

_second() was post to first()

>>> test()

Call the function _second() in _first().

Call the function test() in _second().

'hello world'

>>>
