我对Python编程有点新意，我试图创建一个文本冒险游戏。我假设我使用的是ver 2.7.3？
2.7.3（默认，2015年6月22日，19：33：41） [GCC 4.6.3]
我想制作一个具有最大尺寸的库存系统。我目前正在使用清单列表。
我也想让一些功能成为一次性的东西;您只能选择一个项目而不选择其他项目。
或者在执行之后删除功能？
我认为这些与课程有关，但我并没有在整个课程上取得进步。这是我的代码/游戏的示例。我希望玩家只选择一个武器。
由于我有很多while True个循环，因此可以放心地说玩家可以返回并选择另一个weaponKind。

这里有一些代码可以让你的游戏开始，包括一个很好的基于类的解决方案来解决你的问题，并清理你的代码，这样你就没有一堆随机逻辑，这些逻辑在下周对你来说难以理解。我相信你在这里会有很多不明白的东西。谷歌他们所有，并改变任意代码行并运行它以查看会发生什么。享受！
