发生异常：AttributeError'Class'对象没有属性'Method'

Question

我有一个字符类，里面有这个全名方法。

def FullName(self):
            #Name + title
            return '{}'.format(self.name) 

当我尝试调用它时，出现以下错误：

发生异常：AttributeError'Character'对象没有属性'FullName'

我已经创建了一个名为player的角色类实例。

这就是我所说的

        player.FullName(player)

字符类中的所有方法都是相同的。 我不确定自己在做什么错

class Charcter():
#Setup for charcters
def __init__(self, name, Cclass, damage, damageType, 
health, speed, abilty):
    #Player properties
    self.name = name
    self.Cclass = Cclass
    self.damage = damage
    self.damageType = damageType
    self.health = health
    self.speed = speed
    self.abilty = abilty

    #Invetory list
    Invetory = list()

    def FullName(self):
        #Name + title
        return '{}'.format(self.name)

    def ShowInventory(self):
        #Print every item in inventory
        for Item in Invetory:
            print(Item)

    def Death(self, Enemy):
        print("You have died fighting a " + Enemy.name)
        print("Game over")
        print("Press enter to load from a checkpoint")
        input("")
        #Load check point

    def Battle(self, Enemy):
        print(self.name + " Vs. " + Enemy.name)

Answer 1

好的，所以我终于找到了。 它已经在您发布的第一个代码中了，但是我认为这只是Stackoverflow上此处格式的问题。 事实证明，您的整个问题在于缩进。 但是让我们一次迈出一步。

因此，在Character类中，方法定义位于 init 内部 。 这就是为什么它们不属于班级的原因，以及后来的播放器不具有这些属性的原因。

因此它必须如下所示：

class Character():
    # Setup for charcters
    def __init__(self, name, Cclass, damage, damageType,
             health, speed, abilty):
        # Player properties
        self.name = name
        self.Cclass = Cclass
        self.damage = damage
        self.damageType = damageType
        self.health = health
        self.speed = speed
        self.abilty = abilty
        self.Inventory = {}

    def FullName(self):
        # Name + title
        return '{}'.format(self.name)

    def ShowInventory(self):
        # Print every item in inventory
        for Item in self.Invetory: ## fixme
            print(Item)

    def Death(self, Enemy):
        print("You have died fighting a " + Enemy.name)
        print("Game over")
        print("Press enter to load from a checkpoint")
        input("")
        # Load check point

    def Battle12(self, Enemy):
        print(self.name + " Vs. " + Enemy.name)

另请注意，库存是对象的属性，该属性初始化为空。 因此，您还必须稍后在ShowInventory方法中使用self.Inventory访问它。

我发现的最后一件事是，您错误地创建了敌人。 青蛙可能应该是青蛙类而不是第二只老鼠，您可以使用super(CHILD, self).__init__(...)来调用父类的super(CHILD, self).__init__(...) 。 因此，我将您的Enemy类更改为如下所示：

class Rat(Enemy):
    def __init__(self):
        super(Rat, self).__init__("Rat", 1, 2, "")


class Frog(Enemy):
    def __init__(self):
        super(Frog, self).__init__("Frog", 1, 2, "")

为了简洁起见，我只是省略了关键字。 另外，如果您的父init需要值，则需要给它三个值（您忘了能力，我现在只给了一个空字符串）。

到目前为止，这就是我发现的全部。

Answer 2

我假设您正在这样做：

player = Player()
player.FullName(player)

这就是问题所在

在调用类的函数时，无需传递类的对象。

self指的是新创建的对象（自身），即调用其方法的实例。

因此调用：

full_name = player.FullName()
print "Full name : {}".format(full_name)

一个建议：尽管可以使用FullName函数，但使用变量可能就足够了。
