如何简化这个战舰程序？ （Python）[关闭]

Question

请耐心等待，我是编程新手，我知道其中包含很多不必要的代码。

有没有一种方法可以添加更多船只而无需永久扩展代码？ 也是在我的 while 循环下编写比较代码的更好方法。感谢您抽出宝贵时间阅读和评论。

您需要以更灵活的方式存储“游戏状态”。决定玩家何时获胜的逻辑也是如此。一种方法是将您的应用程序分解为classes，可能类似于：

• Battle class：包含双方战舰、计分方法、战区尺寸
• 船舶等级：船舶大小、船舶遭受的损坏程度、船舶位置

每当创建一个新的 Battle 类时，您都可以向其传递双方的初始舰船列表。这些列表可以任意长（前提是舰船可以在不重叠的情况下进入战场）。
