何时使用"raise NotImplementedError"?

问题描述

是否在提醒自己和您的团队正确实施课堂?我没有完全使用这样的抽象类:

Is it to remind yourself and your team to implement the class correctly?I don't fully get the use of an abstract class like this:

class RectangularRoom(object):
    def __init__(self, width, height):
        raise NotImplementedError

    def cleanTileAtPosition(self, pos):
        raise NotImplementedError

    def isTileCleaned(self, m, n):
        raise NotImplementedError

推荐答案

文档说明 ，

请注意，尽管主要说明的用例是该错误是对应该在继承的类上实现的抽象方法的指示，但您可以随意使用它，例如用于指示TODO标记.

Note that although the main stated use case this error is the indication of abstract methods that should be implemented on inherited classes, you can use it anyhow you'd like, like for indication of a TODO marker.
