Question

作为一个相对较新的程序员，我决定将一个小文本冒险作为我的第一个项目。它工作正常，除非你试图去北方。我收到上面的错误发布。我认为这与变量位置有关，但我不确定。

问题是当你第一次去北方时，你的当前位置被设置为字符串"CaveEntrance"而不是CaveEntrance对象。

更改此行：

Beach = Room("Beach", "The beach. The sand is warm and the water is inviting.",
             "Lantern", "CaveEntrance")

要：

Beach = Room("Beach", "The beach. The sand is warm and the water is inviting.",
             "Lantern", CaveEntrance)

Python错误'对象字符串没有功能'
