Question

我正在尝试根据用户输入使用变量来调用对象属性。这是一款文字游戏。例如，想法是玩家键入“帽子”，此功能检查玩家对象的self.inventory = []中名为“帽子”的Item对象，如果存在这样的对象，它将把Item对象附加到玩家对象的对应属性，在这种情况下为self.helm = []。

为此，我尝试使equipItem等于装备类的类类型的变量，该类类型应与玩家对象的装备属性之一相同。

move = input("To equip, unequip, or an use item, type [item name]. To trade 
in item for XP, type 't [item name]'. Type 'x' to exit inventory: 
").lower().split()

print(move[0])

for i in currentPlayer.inventory:
     print(i.name)
     if i.name == move[0]:
         print(i)
         equipItem = i.itemClass
         currentPlayer.equipItem.append(i)
         currentPlayer.inventory.remove(i)
         print(currentPlayer.equipItem)

但是，这当然会引发错误，因为不是玩家属性中的“ equipItem”。所以我的问题是我如何才能获得想要的结果？我可以使用变量来调用对象属性吗？

我知道这很可能很老套，无论如何我都不喜欢这种方法，所以也欢迎其他方法的建议！

下面的玩家类和物品类：

class Player:
    def __init__(self, name):
        self.name = name
        self.health = 10
        self.maxHealth = 10
        self.inventory = [Item(1, 1), Item(2, 2)]
        self.weapon = [Item(0, 1)]
        self.helm = [Item(1, 0)]
        self.shield = [Item(5, 0)]
        self.boots = [Item(3, 0)]
        self.greaves = [Item(4, 0)]
        self.gloves = [Item(6, 0)]
        self.cuirass = [Item(2, 0)]
        self.defaultPotion = []
        self.attack = 5 + self.weapon[0].attack
        armorClass = self.helm[0].defense + self.shield[0].defense + 
        self.boots[0].defense + self.greaves[0].defense + 
        self.gloves[0].defense 
        + self.cuirass[0].defense
        self.defense = 1 + armorClass
        self.level = 1
        self.experience = 0
        self.offensiveMagic = 0
        self.defenseiveMagic = 0
        self.offensiveCombat = 0
        self.weightClass = 10

    def __str__(self):
        return self.name

class Item:

    def __init__(self, itemType, subType):
        #denotes type of item (wepaon, gloves, etc)
        self.itemType = allItems[itemType]
        #denotes item name and stats (sword, attack value, etc)
        self.subType = self.itemType[subType]
        #denotes how item is used (euip, consume, etc)self.subType = 0:
        if subType == 0:
            self.itemClass = 'weapon'
        elif subType == 1:
            self.itemClass = 'helm'
        elif subType == 2:
            self.itemClass = 'cuirass'
        elif subType == 3:
            self.itemClass = 'boots'
        elif subType == 4:
            self.itemClass = 'greaves'
        elif subType == 5:
            self.itemClass = 'shield'
        elif subType == 6:
            self.itemClass = 'gloves'
        self.name = self.subType['name']
        self.attack = self.subType['attack']
        self.defense = self.subType['defense']
        # self.equip = 'no'

    def __str__(self):
        return self.itemType
        return self.name
        return self.attack
        return self.defense

要通过名称获取对象的属性，请使用getattr内置函数。例如：getattr(currentPlayer, equipItem).append(i)。要分配给属性，请使用setattr。

尝试使用基于输入的变量调用类属性
