class NewClass(ParentClass): def __init__(self, arguments_new_class, arguments_parent_class): super().__init__(arguments_parent_class) # Code for initializing an object of the new class. super()函数会自动将self参数传递给父类。你也可以通过用父类的名字实现,但是需要手动传递self参数。如下所...
Hierarchical Inheritance: more than one child class are created from a single parent class. Hybrid Inheritance: combines more than one form of inheritance. Uses of Inheritance Code Reusability: Since a child class can inherit all the functionalities of the parent's class, this allows code reusabili...
例如: MAX_OVERFLOW 和 TOTAL。 7.3.10 Designing for inheritance 继承的设计 始终要考虑到一个类的方法和实例变量(统称:属性)应该是共有还是非共有。如果存在疑问,那就选非共有;因为将一个非共有变量转为共有比反过来更容易。 公共属性是那些与类无关的客户使用的属性,并承诺避免向后不兼容的更改。非共有属...
Derive exceptions from Exception rather than BaseException . Direct inheritance from BaseException is reserved for exceptions where catching them is almost always the wrong thing to do. Design exception hierarchies based on the distinctions that codecatchingthe exceptions is likely to need, rather than ...

(3)最后一种在mp文档当中没有单独提出,但是在其中多次提到,而且是mp库当中最重要的一种共享方式,称为inheritance,即继承,对象在 父进程当中创建,然后在父进程是通过multiprocessing.Process创建子进程之后,子进程自动继承了父进程当中的对象,并且子进程对这 些对象的操作都是反映到了同一个对象。
Code Lay-out|代码布局 Indentation|缩进 使用每个缩进级别4个空格。 连续行应该使用垂直对齐括号、方括号和花括号内的元素,可以使用Python的括号内隐式行连接,也可以使用悬挂缩进 [1]。使用悬挂缩进时,应考虑以下事项:第一行不应有参数,并且应使用进一步的缩进清晰地表示它是一行的延续。
