我在做一个Python文字冒险游戏。需要帮助制作“背包”
我正在制作一个Python文本冒险游戏。这个游戏是基于《Learn Python the Hard Way》中的第41个练习，所以和那个有点相似。不过，我的问题和那个练习没有关系。我想做一个物品清单，这样玩家就可以捡起物品并使用它们（比如钥匙或者空气清新剂）。
最开始我的计划是用一个布尔变量，也就是用True和False来表示物品是否被“捡起”。但是，这个方法似乎不太奏效。我觉得问题在于，一旦我离开房间，这个值就会重置。
现在我尝试使用一个列表，当物品被“捡起”时，就把这个物品添加到清单里。
我该如何制作一个物品清单，或者至少如何“捡起”一个物品，然后在之后“使用”它呢？
我认为需要关注的代码行是18到20行（在def __init__(self, start)下面），77行（在def cell(self)下面），以及161到162行（在def janitor(self)下面）。

如果你试着把它定义成一个列表，比如说（我猜这是在用Python）
def inventory[]
inventory.append
add item (inventory)
我记不太清怎么把它加到库存里，但这些是基本的内容

如果你把库存定义成一个列表（我就是这么做的），那么你可以这样操作：
class Attributes:
def __init__(self, inventory):
self.inventory = inventory
Player = Attributes([])
Player.inventory.append("Febreeze")
方括号用来创建这个库存，而“append”这个词就是用来往里面添加Febreeze的。

你的方法看起来不错，但有几个小错误。在cell()这个函数里，在elif "febreeze"...这行的后面需要加一个:，也就是在注释开始之前。另外，在这个elif块的最后，你需要加上return 'cell'。做了这些修改后，我就可以拿到Febreeze并使用它了。
