Python的class允许你从零开始创建一个定制类,就像创建Athlete类那样。不过,class还允许通过继承现有的 其他类来创建一个类,这也包括list,set和dict提供的Python内置数据结构类。通过继承创建的这些类称为子类。 classNameList(list):def__init__(self, a_name): list.__init__([]) self.name=a_name 定义了Na...
谈到 init 方法,它是一个特殊的函数,每当实例化该类的新对象时都会调用它。您可以将其视为 initialize 方法,或者如果您来自任何其他面向对象的编程背景,例如 C++、Java等,则可以将其视为构造函数。现在当我们在类中设置方法时,它们会自动接收实例。让我们继续使用 python 类并使用此方法接受名字、姓氏和薪水。

即“initialize(初始化)”,它的作用是将类的属性分配每个对象。 我们根据 Car 类,创建 a、b 两个对象: # 创建类 classCar: def __init__(self, brand, color): self.brand = brand self.color color def start(self): return "Started def stop(self): return "Stopped" # 根据类创建对象 a = ...
