Object Oriented Programming (Python) Questions and Answers Already Passed

Object Oriented Programming (Python) Questions and Answers Already Passed What is Object-Oriented Programming (OOP) in Python? OOP is a programming paradigm that uses objects and classes to structure code, allowing for more modular, reusable, and maintainable programs. What is a class in Python? A class in Python is a blueprint for creating objects, defining methods and properties that the objects will have. What is an object in Python? An object is an instance of a class, containing data and methods that operate on the data. What is the `__init__` method in Python? The `__init__` method is a special method used to initialize an object when it is created. It acts as a constructor in Python classes. What is inheritance in Python? 2 Inheritance allows a class to inherit properties and methods from another class, enabling code reuse. The child class inherits from the parent class. What is polymorphism in Python? Polymorphism allows objects of different classes to be treated as objects of a common superclass, usually by overriding methods in the child classes. What is encapsulation in Python? Encapsulation is the concept of restricting direct access to some of an object's attributes and methods, typically by using private and public access modifiers. What is abstraction in Python? Abstraction is the process of hiding the complex implementation details and showing only the necessary functionality to the user. How do you create a method in Python? A method in Python is created by defining a function inside a class. It typically takes `self` as the first argument to refer to the current instance of the class. 3 What does `self` represent in Python methods? `self` refers to the current instance of the class and is used to access the attributes and methods of the class. How do you create a subclass in Python? A subclass is created by defining a class that inherits from another class, using the syntax: ```python class SubClass(ParentClass): pass ``` What is method overriding in Python? Method overriding allows a subclass to provide a specific implementation for a method that is already defined in its parent class. What is a class variable in Python?
