python设计模式（十九）：备忘录模式

备忘录，定义是：在不破坏封闭的前提下，捕获一个对象的内部状态，并在该对象之外保存这个状态。这样以后就可将该对象恢复到原先保存的状态。简单来说在运行过程中我们可以记录某个状态，当遇到错误时恢复当前状态，这在业务流程中是用设计来处理异常情况。示例code： class AddNumber: def __init__(self): &...

21、Python与设计模式--备忘录模式

一、游戏进度保存打过游戏的朋友一定知道，大多数游戏都有保存进度的功能，如果一局游戏下来，忘保存了进度，那么下次只能从上次进度点开始重新打了。一般情况下，保存进度是要存在可持久化存储器上，本例中先以保存在内存中来模拟实现该场景的情形。以模拟一个战斗角色为例。首先，创建游戏角色。 class GameCharacter(): vitality = 0 attack = 0 ...
