A.class_foo('a') # cls是一个类,类方法可以只传入一个参数x来调用 # 方法二:通过实例化对象来调用 b = A("tom") b.class_foo("a") 输出结果: executing class_foo(<class '__main__.A'>, a) cls: <class '__main__.A'> 0 executing class_foo(<class '__main__.A'>, a) cls: ...
1.直接写类名调用: parent_class.parent_attribute(self) 2.用 super(type, obj).method(arg)方法调用:super(child_class, child_object).parent_attribute(arg) 【不需要写self】 3.在类定义中调用本类的父类方法,可以直接 super().parent_method(arg) 【个人推崇这种写法】 样例如下: 1 2 3 4 5 6 7...
