Python类Shenanigans

Question

我不知道如何解决这个问题。我在Python中编写脚本非常新，所以我可能只是忽略了一些东西或只是一个全面的菜鸟。 有人可以解释我的代码有什么问题吗？

我的想法是创建两种类型的对象，房间和项目。这很有效，我在最后创建了一个房间和两个项目。然后，我们的想法是将一个项目放入一个房间的库存中，该库存实际上是一个对象列表。但是，我似乎无法将对象添加到房间。我已经尝试过解决我的课程的不同属性，但我没有尝试过任何工作！

请帮帮忙？ ：）

首先，DON＆＃39; T使用全局变量。而只是在你的主要声明变量。

if __name__ == "__main__":
    myroom = Room("Ground Zero", "First empty room")
    ...
