所以Python继承(Inheritance)的概念就是将各类别(Class)会共同使用的属性(Attribute)或方法(Method)放在一个独立的类别(Class)中，其它的类别(Class)透过继承(Inheritance)的方式来拥有，降低程式码的重复性。Python继承(Inheritance)的重要观念如下：如何使用Python继承(Inheritance)方法覆写(Method Overriding)多层继承(Mul...

多类继承 multi-Inheritance 如果你想调用父类函数,可以这样: 19、垃圾收集——内存管理 Python 中的所有对象都存储在一个堆积空间 (heap space),而 Python 解释器可以访问此空间。 Python 有一个内置的垃圾收集机制。 这意味着 Python 可以自动为程序进行分配和取消内存,这与 C++ 或 C# 等其他语言类似。

Python allows you to create multi-level inheritance hierarchies with dataclasses. You can define a child class that inherits from another child class, which in turn inherits from a parent dataclass, enabling you to build complex class relationships. 5. Are there any limitations or considerations ...
The process of inheriting the properties of the parent class into a child class is called inheritance. Learn Single, Multiple, Multilevel, Hierarchical Inheritance in Python
