我正在做一個蟒蛇文字冒險。製作「庫存」需要幫助

Question

我在做一個python文本冒險。它基於學習Python困難方式中的ex41，因此它有點類似。但是，我的問題與這個練習無關。我正在努力製作一份清單，以便可以拾取和使用一件物品（即鑰匙或少女）。

起初，我的計劃是使用一個布爾變量，以便當該項目被「拾取」時，它會將值設置爲True，但它似乎不起作用。我認爲問題在於，一旦我離開房間，價值就會重置。

現在我正在嘗試一個列表，當物品被「拾取」時，該物品被添加到庫存清單中。

我該如何製作庫存，或者至少是「拿起」一個物品，然後「使用」它？

我認爲重要的代碼行是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，但你有幾個錯誤。在cell()中，在elif "febreeze"...聲明（註釋開始之前）之後需要:。另外，在elif區塊末尾，您需要return 'cell'。有了這些變化，我可以拿起Febreeze並使用它。

Answer 2

如果你tryed將其定義爲一個列表，如（猜這是蟒蛇）

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

不能的rember如何將它添加到庫存，但有基本

Answer 3

如果定義庫存作爲一個列表（這就是我所做的那樣），那麼你可以做：

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

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

方括號做庫存，而「追加」補充Febreeze它。
