Inheritance is a powerful feature in object oriented programming. It refers to defining a new class with little or no modification to an existing class. The new class is called derived (or child) class and the one from which it inherits is called the base (or parent) class.
In this tutorial, you'll learn all about object-oriented programming (OOP) in Python. You'll learn the basics of the OOP paradigm and cover concepts like classes and inheritance. You'll also see how to instantiate an object from a class.
15 Ιαν 2024 · In this step-by-step tutorial, you'll learn about inheritance and composition in Python. You'll improve your object-oriented programming (OOP) skills by understanding how to use inheritance and composition and how to leverage them in their design.

A very useful application of inheritance is to create subclasses that inherit from some of the Python built-in classes, to extend them into a more specialized class. For example, if we want to create a custom class similar to the built-in class list, we just must create a subclass that inherits from list and write the new methods we want to add:
inheritance or subtyping describes when an object can be used in place of another. A mixin class is a class that’s intended to provide an optional interface or methods to other classes without having to be the parent class of those other classes.
• Introduces Python’s special methods to realize class definition, inheritance, multiple inheritance, accessibility, polymorphism, encapsulation. • This presentation indicates the difference of how to realize OOP method between python and other OOP language • Compare Python’s OOP methods with other OOP languages.
