关于类：python解释器在没有的情况下抛出类型错误

python interpreter throwing a type error where there is none

我正在尝试在PyGame中创建类似下拉列表的功能。程序由"Drop"类组成，其中包含文本并描述下拉菜单的一般用途。然后是包装类，它在下拉菜单中包含所有不同的标签。子类是标签，可以通过发生错误的"add_child"函数添加到包装类中。

错误：

152，加上孩子self.children.append(child(self，kwargs))。类型错误：init()接受2个位置参数，但给出了3个

你要的是Child(self, **kwargs)，而不仅仅是Child(self, kwargs)。当您需要关键字时，它试图将其作为参数发送。
