话说 Python 官网里面有详细讲装饰器（ decorator）吗？

[HxSeek]

如题··，我在官方文档内（2.X）版本那·· 查找不到···请问是没有？还是我找不到而已。 如果官方文档没有··大家是看什么入门decorator的？

不懂 decorator, 不过 lz 的问题可以搜索 decorator site:python.org :)
另，找到一个教程， http://www.cnblogs.com/vamei/archive/2012/09/13/2682778.html

你还要多详细，本来就没多少东西，就一语法糖

[yourmoonlight]

@f1(arg)
@f2
def func(): pass
is equivalent to:

def func(): pass
func = f1(arg)(f2(func))

[zonyitoo]

decorator就是一个语法糖来的而已呀

[yourmoonlight]

python decorators are equated to macros.

the goal of macros is to provide a way to modify elements of the language.

that's what decorators do in python, they modify functions, in the case of class decorators, entire classes.

的确只是语法糖而已，nothing more

原来如此··小白就此谢过大家的回复啦··

虽然lz已经原来如此了，还是留下个觉得有用的链接 https://www.python.org/dev/peps/pep-0318/
