Understanding Object-Oriented Programming 2

What is Object-Oriented Programming (OOP)?

• Object-Oriented Programming (OOP) is a programming paradigm that uses 'objects' to design applications.

• A method for writing procedural code

• A way to create static functions

• A programming language that only uses variables

How is OOP different from procedural programming?

• OOP focuses on functions, while procedural programming focuses on data.

• OOP is only used in web development, while procedural programming is used in desktop applications.

• OOP does not support inheritance, while procedural programming does.

• OOP uses objects and classes, while procedural programming uses procedures and functions.

What are the benefits of using OOP in Python?

• Increased execution speed and performance

• Encapsulation, inheritance, polymorphism, and improved code organization.

• Simplified syntax and reduced code length

• Direct access to hardware resources

Define a class and an object in Python.

• class Cat: pass

• class Animal: def __init__(self): pass

• class Dog: pass my_dog = Dog()

• my_cat = Cat()

How do you create a class in Python? Write an example.

• class MyClass(value):

• class MyClass[]:

• def MyClass():

• class MyClass: def __init__(self, value): self.value = value def display(self): print(self.value)

How do you create an object of a class?

• Use 'create ClassName()' to instantiate an object.

• Use 'new ClassName()' to create an object of a class.

• Call 'ClassName.new()' to generate an object.

• Invoke 'new Object(ClassName)' to create an instance.

What is the purpose of the __init__ method?

• To create a new class in Python.

• To define a class's methods and functions.

• To delete an object from memory.

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

What are instance variables?

• Instance variables are attributes that belong to an instance of a class.

• Instance variables are global variables accessible from anywhere.

• Instance variables are static attributes shared across all instances of a class.

• Instance variables are methods that perform actions on a class.

What are instance methods?

• Instance methods are functions that belong to an instance of a class and can access instance-specific data.

• Instance methods are static functions that do not access instance data.

• Instance methods are global functions that can be called without an instance.

• Instance methods are functions that belong to a class and cannot access instance-specific data.

How do you define a method inside a class?

• method_name: (parameters)

• def method_name(parameters):

• method_name(parameters) =>

• method_name(parameters) {
