Understanding Python OOP Basics

What is a class in Python?

• A class in Python is a way to create variables that hold data.

• A class in Python is a built-in data type for storing numbers.

• A class in Python is a function that returns a value.

• A class in Python is a template for creating objects that define attributes and methods.

Define an object in the context of OOP.

• An object is a function that performs actions on data.

• A class is a blueprint for creating objects.

• An object is an instance of a class that contains data and methods.

• An object is a type of variable that holds a single value.

How do you create a method in a Python class?

• Implement a method using 'def method_name():' without 'self'.

• Use 'create method_name(self):' to define a method.

• Declare a method with 'method_name():' outside the class.

• Define a method using 'def method_name(self):' inside the class.

What is the purpose of the __init__ method?

• To initialize an object's attributes when an instance of a class is created.

• To create a new class in Python.

• To define a class's methods and functions.

• To delete an object when it is no longer needed.

Explain the concept of inheritance in OOP.

• Inheritance is a method for creating new classes without any relationship to existing ones.

• Inheritance allows a class to inherit only private methods from another class.

• Inheritance allows a subclass to inherit attributes and methods from a superclass, promoting code reuse and establishing a class hierarchy.

• Inheritance is the process of copying code from one program to another without any structure.

Why is encapsulation important in OOP?

• Encapsulation is not relevant in modern programming languages.

• Encapsulation is only about hiding methods.

• Encapsulation enhances data protection and modularity in object-oriented programming.

• Encapsulation reduces the performance of the program.

What are the benefits of using OOP in programming?

• Increased execution speed

• Simplified syntax for all programming languages

• Automatic error correction during runtime

• Benefits of OOP include code reusability, encapsulation, polymorphism, improved maintainability, and better organization of code.

How does polymorphism enhance code flexibility?

• Polymorphism restricts methods to a single class type.

• Polymorphism increases code complexity by requiring multiple interfaces.

• Polymorphism enhances code flexibility by allowing methods to operate on objects of different classes through a common interface.

• Polymorphism eliminates the need for inheritance in object-oriented programming.
