类型错误：__init__() 需要 1 个位置参数，但给出了 2 个（无继承）

Question

虽然似乎有几个人已经回答了这个问题，但他们往往指的是继承。 我收到错误： TypeError: __init__() takes 1 positional argument but 2 were given在我运行此段时TypeError: __init__() takes 1 positional argument but 2 were given ：

class game:
    def __init__(self):

        self.x = 1
        drawPile = deck(playerCount)

这段代码：

如果我投入了我的大部分程序，我深表歉意。

Answer 1

当您调用甲板构造函数时，您正在尝试传递一个参数，在这一行中：

drawPile = deck(playerCount)

但是您将甲板构造函数声明为不带任何参数，除了 self：

class deck:
    def __init__(self):

这就是 Python 所抱怨的，但错误消息的实际文本让初学者感到困惑。 由于deck 是一个类而不是函数，Python 会自动向构造函数调用添加第一个参数self。 这就是为什么错误消息说“需要 1 个位置参数，但给出了 2 个”。 错误消息将“self”计为一个参数。 由于您试图提供另一个，这意味着“提供了两个”。

Answer 2

您的playerCount变量是全局变量，因此在创建deck对象时无需将其作为参数传递。 因此，只需将类game替换为以下几行：

class game:
    def __init__(self):
        global drawPile  
        self.x = 1
        drawPile = deck()
