This brings us to inheritance, which is a fundamental aspect of object-oriented programming. 这就引出了继承,这是面向对象编程的一个基本方面。 Inheritance means that you can define a new object type, a new class, that inherits properties from an existing object type. 继承意味着您可以定义一个新...
In Python, an object is a specific instance of a class that holds data (attributes) and performs the same actions (methods) that are specified by the class. Each object has its own data, but uses the same method defined in the class. Steps to create an object: Define a class ...

You create an object in Python by instantiating a class, which involves calling the class name followed by parentheses. Class inheritance in Python allows a class to inherit attributes and methods from another class, known as the parent class. You use super() in Python to call a method from...
