웹 문서를 제작할때면, 몇 마디 수사를 해줄 필요가 있을 때 이 decorator function을 쓰게 되면 효율적입니다.

LC training(1:55) - Now since you guys are sending it to me for Christmas maybe you want to wrap the gpu So you might have a new function and we'll say define add wrapping When you wrap something you're wrapping right you're wrapping something So you're gonna pass whatever the item is that you want to wrap into this wrapping function And now we're going to say we're gonna define wrapped underscore item and what this is gonna do is return a wrapped up box of something and then will do dot format string version of whatever the item is So we return that and then now at the that for the actual add wrapping function we're gonna return wrapped item So now what we can do is at new gpu we can wrap it So we can say boom add wrapping and that will decorate our wrapping paper to our new Tesla P100 gpu So we can now run literally new gpu nothing changes We've just added that wrapping with the decorator
