# ******************** day25-静态、组合、继承 *******************

# =====>>>>>>内容概览

# =====>>>>>>内容概览

# ------------------------------------------------------------

# # 1、对于类中的函数属性调用

# # # 实例调用函数属性，调用时类会自动传入参数self

# # # 类  调用函数属性，调用时类不会自动传入参数self，需要自己传入参数

# # #

# # # 需要注意的是，实例有数值属性，但是没有函数属性，它的函数调用都是对类函数调用

# # # 而类中是有函数属性 + 数值属性

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 2、静态属性引入

# # #

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 2.1、静态属性引入1

# # # 把特定功能封装成一个函数

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 2.2、@property，静态属性引入2

# # # 把特定功能封装成一个函数，使用@property来修饰的时候，在调用上可以不用()就可以运行，

# # # 看起来像是一个数值属性

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 2.3、@property，静态属性引入3

# # # 把特定功能封装成一个函数，使用@property来修饰的时候

# # # 看起来像是一个数值属性

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 3、通过实例化，对类的方法进行调用

# # # 通过实例化，对类的方法进行调用，这个过程中，实例化的作用只是桥梁

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 4、classmethod，"不" 通过实例化，对类的方法进行调用

# # # classmethod所修饰的函数A，实例仍然可以访问, 但是它与实例是没有任何的关系的，并且，函数A

# # # 只能访问类的属性而不可以访问实例的属性

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 5、classmethod，"不" 通过实例化，对类的方法进行调用

# # # 所修饰的函数，实例仍然可以访问

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 6、类中的staticmethod

# # # 被修饰的函数脱离于类、 实例的绑定

# # # 类中被类中的staticmethod的函数属性，是属于类的工具包，它对于类中的所有其他属性都是

# # # 不绑定的，也不与类中的实例绑定，这个时候，他就相当于一个普通的函数，仅仅是用来给类

# # # 特定的提供一些方法，但却不属于类的特征属性

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 7、组合

# # # 定义一个人的类，人有头，手，脚等数据属性，这几个属性又可以是通过一个类实例化的对象，这就是组合

# # #

# # # 用途：

# # # 1：做关联

# # # 2：小的组成大的

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 8、组合1

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 9、组合应用，给区域学校添加课程

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 10、组合应用，给区域学校添加课程2

# # 这个通过的是列表来实现，相对于上面那种，差了一些

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 10.1、组合应用，给区域学校添加课程2

# # 这个通过的是列表来实现，相对于上面那种，差了一些

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 10.2、组合应用，给区域学校添加课程2

# # 这个通过的是列表来实现，相对于上面那种，差了一些

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 11、类的继承--数值属性继承

# # #

# # # 类的继承跟现实生活中的父、子、孙子、重孙子、继承关系一样，父类又称为基类

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 12、类数值属性继承1

# # # 以下列例子为基础，数值属性查找：如果son中有数值属性，那么，就会使用自己的，如果没有，

# # # 就回去Dad类中找

# # # 如果是Dad类中有添加数值属性，Son是继承了Dad类的，如果本身没有的话，仍然能够去Dad类中查找

# # # 本质上，两者的数值属性是相互独立

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 13、类函数属性继承

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 14、类函数属性继承2

# # # Dad类与继承类Son中，如果Son中有自己的函数属性就用自己的

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 15、接口继承引入

# # # 所有的类都有一个共同的属性方式，这个时候，可以将他们提取出来，放到同一个类当中，作为一

# # # 个基类

# # # 这个属于：继承基类的方法，并且做出自己的改变或者扩展（代码重用）

# # # 但是意义并不是很大，甚至常常是有害的，因为它使得子类与基类出现强耦合；

# # # 因此少用

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 15.1、 @abc.abstractmethod, 接口继承

# # # 以下面为例子，所有类中的共同有的函数属性--write、read全部提取出来到，All_file类中

# # # 通过@abc.abstractmethod进行修饰，所有的继承的类必须要有这个函数

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 15.2、 接口继承中，继承者缺少被继承者要求的函数

# # # 继承者==son类，被继承者==parent类，如果继承过程中，parent类接口要求2个函数属性，

# # # son中有1个，会报错

# # # 下面例子，

# # # 被继承者 == All_file；   继承者 == Mem    Directory

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 15.3、 接口继承中，继承者有被继承者要求的函数之外，还有其他函数属性

# # # 以下面为例子，所有类中的共同有的函数属性--write、read全部提取出来到，All_file类中

# # # 通过@abc.abstractmethod进行修饰，所有的继承的类必须要有这个函数，

# # # 但是，继承者在这个基础上可以有其他的函数

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 16、继承顺序引入( 新式类，广度优先)

# # # 继承结构：分支一： F --> D --> B --> A;

# # #           分支二： F --> E --> C --> A;

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 16.1、继承顺序引入

# # # 继承结构：分支一： F --> D --> B --> A;

# # #           分支二： F --> E --> C --> A;

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 16.2、继承顺序引入

# # # 继承结构：分支一： F --> D --> B --> A;

# # #           分支二： F --> E --> C --> A;

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 16.3、继承顺序引入

# # # 继承结构：分支一： F --> D --> B --> A;

# # #           分支二： F --> E --> C --> A;

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 16.4、继承顺序引入

# # # 继承结构：分支一： F --> D --> B --> A;

# # #           分支二： F --> E --> C --> A;

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 16.5、继承顺序引入

# # # 继承结构：分支一： F --> D --> B --> A;

# # #           分支二： F --> E --> C --> A;

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 16.6、总结：继承顺序引入

# # # 继承结构：分支一： F --> D --> B --> A;

# # #           分支二： F --> E --> C --> A;

# # # 这种方式称之为：广度优先！python3中的所有的类都是新式类,python2x中的是经典类

# # # 新式类：满足class A(object)，即父类是object类_main__.A'>, <class 'object'>(见序号17中的print(F.__mro__) ),

# # # python3中都是新式类，因此   class A == class A(object)

# # # 经典类：？？？？

# # # 当类是经典类时，多继承情况下，会按照深度优先方式查找

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 17、继承顺序的的确定

# # # Python到底是如何实现继承的，对于你定义的每一个类，Python会计算出一个方法

# # # 解析顺序（MRO）元组，这个MRO元组就是一个简单的所有基类的线性顺序列表

# # #

# # # 继承结构：分支一： F --> D --> B --> A;

# # #           分支二： F --> E --> C --> A;

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 18、继承顺序引入( 经典类，深度优先)

# # # 经典类： class A； 新式类：class A(object)

# # # 继承结构：分支一： F --> D --> B --> A;

# # #           分支二： F --> E --> C --> A;

# # #

# # # 编译环境python2.7( 没有标注的都是python3)( 没有标注的都是python3)

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 18.1、继承顺序引入

# # # 继承结构：分支一： F --> D --> B --> A;

# # #           分支二： F --> E --> C --> A;

# # #

# # # 编译环境python2.7( 没有标注的都是python3)

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 18.2、继承顺序引入

# # # 继承结构：分支一： F --> D --> B --> A;

# # #           分支二： F --> E --> C --> A;

# # #

# # # 编译环境python2.7( 没有标注的都是python3)

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 18.3、继承顺序引入（与16.3对比）

# # # 深度优先，会使用分支一找到A

# # # 继承结构：分支一： F --> D --> B --> A;

# # #           分支二： F --> E --> C --> A;

# # #

# # # 编译环境python2.7( 没有标注的都是python3)

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 18.4、继承顺序引入（与16.3对比）

# # # class A: 经典类，深度优先；     class A(object): 新式类，广度优先

# # # 广度优先，B找不到，回来通过E找，后面的同python3的情况

# # # 继承结构：分支一： F --> D --> B --> A;

# # #           分支二： F --> E --> C --> A;

# # #

# # # 编译环境python2.7

# ------------------------------------------------------------

# # 19、子类与父类中__init__有重复

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 20、关于self自动传入参数的情况：1、实例化； 2、对象调用类方法

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 21、子类与父类中__init__重复解决方式

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 22、子类调用父类的方法

# ------------------------------------------------------------

# ------------------------------------------------------------

# # 23、super调用父类的方法

# # # =====>>>>>>上面的那种子类调用父类的方法还不够好

下面的1、2、3的表达方式是等价的

1、super().__init__(name, speed, load, power)

2、super(__class__,self).__init__(name,speed,load,power)     # __class__是类名，见# print(line13.__class__)

3、super(Subway,self).__init__(name,speed,load,power)

# # # 新式类：满足class A(object)，即父类是object类_main__.A'>, <class 'object'>(见序号17中的print(F.__mro__) ),

# # # python3中都是新式类，因此   class A == class A(object)

# # # 经典类：？？？？

# # # 当类是经典类时，多继承情况下，会按照深度优先方式查找
