In this case, you use@add_messagesto decorategreet(). This adds new functionality to the decorated function. Now when you callgreet(), instead of just printingHello, World!, your function prints two new messages. The use cases for Python decorators are varied. Here are some of them: ...
Now we come to the most important reason to use inner functions. All of the inner function examples we’ve seen so far have been ordinary functions that merely happened to be nested inside another function. In other words, we could have defined these functions in another way (as discussed);...

function outer() { var inner = "初始值"; function getInner() { return inner; } function setInner(newValue) { inner = newValue; } return { getInner: getInner, setInner: setInner }; } var closure = outer(); console.log(closure.getInner()); // 输出:初始值 clos...
In the previous lesson, I showed you how to use decorators with arguments. In this lesson, I’ll summarize the course. This course covered the idea of defining functions inside of other functions, appropriately enough named inner functions. Inner…
You can't, however, access the outer class in an inner class. Let's see an example below. class Outer: """Outer Class""" def __init__(self): ## instantiating the 'Inner' class self.inner = self.Inner() def reveal(self): ## calling the 'Inner' class function display self....
