![]() What is a constructor in Python? Explain its types.Īnswer: A constructor is a special method in a class that is automatically invoked when an object is created. Data attributes can be simple variables or more complex objects, whereas methods are functions associated with the class.ġ3. Data attributes are accessed using dot notation (object.attribute), while methods are invoked using parentheses (thod()). How are data attributes different from methods in a class?Īnswer: Data attributes represent the state or properties of an object and store values, while methods define the behavior or actions that the object can perform. It represents the instance of the class and allows access to its attributes and methods within the class.ġ2. What is the purpose of the self keyword in Python?Īnswer: The self keyword is used as the first parameter in method definitions within a class. It provides a simplified interface for the users, promoting code modularity and reusability.ġ1. It allows objects to be treated as instances of their own class or any of their parent classes, providing flexibility and code reusability.Īnswer: Abstraction is the process of hiding complex implementation details and exposing only the essential features or behavior of an object or class. It allows the data to be hidden and accessed only through the defined methods, ensuring data integrity and providing abstraction.Īnswer: Polymorphism is the ability of objects of different classes to respond to the same method name. ![]() Python does not support method overloading directly, but it can be achieved using default parameter values or using variable arguments (*args, **kwargs).Īnswer: Encapsulation is the principle of bundling data and methods within a class. The method in the subclass must have the same name and parameters as the method in the superclass.Īnswer: Method overloading refers to the ability of a class to have multiple methods with the same name but different parameters. Hybrid Inheritance: It is a combination of multiple types of inheritance.Īnswer: Method overriding occurs when a subclass provides its own implementation of a method that is already defined in its superclass. Hierarchical Inheritance: Multiple derived classes inherit from a single base class. Multilevel Inheritance: A class inherits from a derived class, which itself inherits from another class. Multiple Inheritance: A class inherits from multiple base classes. Single Inheritance: A class inherits from a single base class. ![]() In Python, there are multiple types of inheritance: Explain inheritance and its types in Python.Īnswer: Inheritance is a mechanism in OOP that allows classes to inherit attributes and methods from other classes. It is a concrete representation of the class with actual data and can perform actions defined by the class.ĥ. An object, on the other hand, is an instance of a class. ![]() What is the difference between a class and an object?Īnswer: A class is a template or blueprint that defines the structure and behavior of objects. An object is an instance of a class that encapsulates data and provides methods to interact with that data.Ĥ. Polymorphism: Providing a single interface to entities of different types.Ībstraction: Hiding complex implementation details and providing simplified interfaces.Īnswer: A class is a blueprint or template that defines the properties and behaviors that objects of a particular type will have. Inheritance: Allowing classes to inherit properties and behaviors from other classes. It emphasizes concepts such as encapsulation, inheritance and polymorphism.Įncapsulation: Bundling data and methods within an object. OOPS Interview Questions and AnswersĪnswer: Object-Oriented Programming (OOP) is a programming paradigm that organizes data and behavior into reusable structures called objects. Whether you are a fresher or an experienced professional, these interview questions will help you showcase your knowledge and expertise in Python OOP. These questions cover a wide range of topics, including OOP concepts, principles, inheritance, polymorphism, encapsulation, and more. To help you prepare for your upcoming interviews, we have compiled a comprehensive list of the top 100 OOPs concept interview questions in Python. As a Python developer, it is essential to have a solid understanding of OOP principles and how they are applied in the Python programming language. ![]() In the world of software development, Object-Oriented Programming (OOP) is a fundamental concept that plays a crucial role in designing and implementing robust and scalable applications. ![]()
