Python 使用类然后调用该类时出错

正如你在这里看到的，我上了一节课

    class Player():
        def __init__(self, name, maxhealth, base_attack, gold, weapon, curweapon, healing_potions):
            player = Player('player', 100, 100, 5, 30, 'Normal Sword', 'Normal Sword', 0 )
            self.name = name
            self.maxhealth = maxhealth
            self.health = self.maxhealth
            self.base_attack = base_attack
            self.gold = gold
            self.weap = weapon
            self.curweapon = curweapon
            self.healing_potions = healing_potions

但是当我试着像这样调用治疗药剂的时候

                    if question == '2':
                        player_in_diningroom = True
                        print("You enter the dining room")
                        print("")
                        print("You find a Potion Of healing on the table!")
                        print("")
                        healing_potions += 1
                        player_in_diningroom = False

然后它给了我这个错误

回溯（最近一次呼叫最后一次）： 文件“c:/Users/Isaiah/Desktop/All-of-my-programs/Role-playing game.py”，第179行，在 治疗药剂+=1 名称错误：未定义名称“治疗药剂”

我不太明白为什么要在player类中初始化player对象。这会导致无限重复，您不断无限地创建玩家实例。 您很可能需要在类之外创建它。我向类中添加了一个方法，这样我们就可以使用属于实例的方法来增加健康药水。这通常是推荐的做法

#player class
class Player():
    def __init__(self, name, maxhealth, base_attack, gold, weapon, curweapon, healing_potions):
        self.name = name
        self.maxhealth = maxhealth
        self.health = self.maxhealth
        self.base_attack = base_attack
        self.gold = gold
        self.weap = weapon
        self.curweapon = curweapon
        self.healing_potions = healing_potions
    def increase_health_potions(self):
        self.healing_potions +=1

然后初始化一个播放器实例/对象。我注意到您在创建的实例中有一个额外的参数，所以我删除了一个以使其正常工作

#create an instance called player
player = Player('player', 100, 100, 5, 'Normal Sword', 'Normal Sword', 0 )

question = '2'
if question == '2':
    player_in_diningroom = True
    print("You enter the dining room")
    print("")
    print("You find a Potion Of healing on the table!")
    print("")
    player.healing_potions += 1 #accesing and increasing variable belonging to instance
    player.increase_health_potions() #call method belonging to instance that increases the variable 
    player_in_diningroom = False

print(player.healing_potions)

注意

player.healing_potions += 1

你必须参考你想要增加生命药水的玩家。

你的方法参数列表是从

self

开始的吗？如果函数在构造函数中，则未指明定义代码的位置。

self.recovering\u potations

。否则它可能类似于您的\u player\u变量。通常，您只使用类内方法的实例字段。方法以Python中的

self

作为参数开始。你能给我一个我这里的代码示例吗？所以当我调用治疗药剂+=1时，我会改为使用self.recovering药剂+=1？非常感谢！很好用！
