In Python, we can extend a class to create a new class from the existing one. This becomes possible because Python supports the feature of inheritance. Using inheritance, we can make a child class with all the parent class’s features and methods. We can also add new features to the chil...
In older Python versions, it’s available with the typing_extensions backports. A Protocol is different from an abstract base class in that it’s not explicitly associated with a concrete class. Instead, it relies on type matching to associate it at type-check time with mypy....

One of the advantages of an Object-Oriented programming language is code reuse. Inheritance is a fundamental concept in object-oriented programming (OOP) that allows a class to inherit attributes and methods from another class. This promotes code reusability and logical structure in your programs. F...

Classes are like a blueprint or a prototype that you can define to use to create objects. We define classes by using theclasskeyword, similar to how wedefine functionsby using thedefkeyword. Info:To follow along with the example code in this tutorial, open a Python interactive shell on ...
# Single inheritance in python #Base class class Parent_class(object): # Constructor def __init__(self, name, id): self.name = name self.id = id # To fetch employee details def Employee_Details(self): return self.id , self.name ...
Inflexibility: Once __slots__ is defined, you cannot dynamically add new attributes to instances. Inheritance complications: If a class with __slots__ is inherited, the subclass must also define __slots__ to continue benefiting from memory optimization, which can complicate the class design. ...
Polymorphism can be carried out throughinheritance, with subclasses making use of base class methods or overriding them. Python’sduck typing, a special case of dynamic typing, uses techniques characteristic of polymorphism, includinglate bindinganddynamic dispatch. The term “duck typing” is derived...
Every object-oriented programming language must acquire some features like inheritance, use of class & objects, polymorphism, encapsulation, data abstraction. These features make the differentiation between a procedural and an object-oriented language. High-level languages like Java and Python allow...
