python - 属性错误: 'int' object has no attribute 'directions'

Question

我已经更新了代码，使其看起来与我的计算机上的完全一样。

我一直在开发一个简单的 Python 文本冒险引擎，但遇到了一个问题。如果您可以解决我的问题或者有更有效的方法来编码/构造方法或类，请告诉我!我对这类事情很陌生，任何建议都会很棒!另外，格式可能达不到标准，但是嘿，我尝试过!

好的，我的项目有两个模块，标题为 Game 和 Map。第一个模块，Game，“解析”用户输入并更改玩家所在的房间。第二个模块，Map，勾勒出一个Room > 包含构造函数和一些与方向、导出等相关的函数的类。我还没有解决移动到一个不存在的房间的问题，我确信我的代码相当糟糕，但这里是:

再次强调，如果你看到什么可怕的东西，请告诉我!这是我在没有任何指导的情况下自己编写的第一个项目。谢谢!

问题出在这里...

if(item == " North" or " north"):

这是测试条件的错误方法。

你需要做的是

if (item == " North") or (item == " north"):

也请查看其他使用“或”检查条件的地方。
