Question

我是Python的新手，我正在通过创建基于文本的游戏来学习类和方法的交互方式。代码运行得很好，但是，我的问题在于Name（object）类。无论我把它放在代码中，（如下所示，在开头或中间）我将始终提示输入。我怀疑可能是因为name_new属性提示raw_input（＆＃34;＆gt;＆＃34;），但是，我想知道在提示类名（）时是否有办法防止或改变。< / p>

class Character(object):

    def __init__(self, name, weapon, spec_ability, health):
        self.name = name
        self.weapon = weapon
        self.spec_ability = spec_ability
        self.health = 100


    def special_ability(self):
        special = False
        rand_num = str(random.choice(rdm))

        if '1' in rand_num or '2' in rand_num or '3' in rand_num:
            special = True
            if special:
                print "Your special ability is ready."
                return True

            else:
                return
        else:
            print "Your special ability is not ready."

    def Critical_Chance(self):
        crit = False
        rand_num = str(random.choice(rdm))


        if '1' in rand_num or '2' in rand_num or '3' in rand_num:

Answer 1

运行程序时，将执行模块级代码。这包括您的Name课程。

class Name(object):
    name_new = raw_input("> ")

这会创建类Name，并且也会在类中执行代码。这就是您提示输入姓名的原因。

如果您希望能够提示用户输入此类名称

verynew_name = Name()

您必须更改Name课程，以便在实例化课程时执行raw_input（因为这是Name()所做的事情，它创建了Name）的实例：

class Name(object):
    def __init__(self):
        self.name_new = raw_input("> ")

（请注意，您必须使用name_choice = Name.name_new而不是name_choice = verynew_name.name_new。

Answer 2

定义Character类的构造函数和不将名称作为参数的子类： e.g。

阶级勇士（角色）：

def __init__(self, weapon, spec_ability, health, armor):
    super(Warrior, self).__init__(weapon, spec_ability, health)
    self.armor = armor

并且在字符类中，您可以将self.name默认定义为None

您可以随后使用类似

之类的内容在逻辑中指定名称

character.name = Name.name_new

只要你在实际读取name的值之前就这样做了，你就没事了

类中的属性会立即在错误的时间运行吗？
