我正在做一个蟒蛇文字冒险。制作“库存”需要帮助

Question

我在做一个python文本冒险。它基于学习Python困难方式中的ex41，因此它有点类似。但是，我的问题与这个练习无关。我正在努力制作一份清单，以便可以拾取和使用一件物品（即钥匙或少女）。

起初，我的计划是使用一个布尔变量，以便当该项目被“拾取”时，它会将值设置为True，但它似乎不起作用。我认为问题在于，一旦我离开房间，价值就会重置。

现在我正在尝试一个列表，当物品被“拾取”时，该物品被添加到库存清单中。

我该如何制作库存，或者至少是“拿起”一个物品，然后“使用”它？

我认为重要的代码行是18-20（在def __init__(self, start)下），77（在def cell(self)下），161-162（在def janitor(self)下）。

Answer 1

你的方法似乎工作正常，但你有几个错误。在cell()中，在elif "febreeze"...声明（注释开始之前）之后需要:。另外，在elif区块末尾，您需要return 'cell'。有了这些变化，我可以拿起Febreeze并使用它。

Answer 2

如果你tryed将其定义为一个列表，如（猜这是蟒蛇）

def inventory[] 
    inventory.append 
add item (inventory) 

不能的rember如何将它添加到库存，但有基本

Answer 3

如果定义库存作为一个列表（这就是我所做的那样），那么你可以做：

class Attributes: 
     def __init__(self, inventory): 
      self.inventory = inventory 

    Player = Attributes([]) 
    Player.inventory.append("Febreeze") 

方括号做库存，而“追加”补充Febreeze它。
