REST APIs with Flask and Python - Object-Oriented Programming in Python

This video tutorial introduces object oriented programming (OOP) in Python, explaining its purpose and how it differs from using dictionaries for data handling. It covers the basics of defining classes and methods, creating and using objects, and introduces advanced concepts like using parameters in the init method. The tutorial emphasizes the benefits of OOP in organizing code and making it more intuitive by mimicking real-world objects.

What is the main purpose of Object Oriented Programming?

• To make code more complex

• To simplify code by modeling real-world entities

• To increase the number of lines of code

• To make programming languages harder to learn

In Python, what keyword is used to define a class?

• def

• class

• method

• function

What is the purpose of the __init__ method in a Python class?

• To print an object's properties

• To initialize an object's properties

• To define a class

• To delete an object

How do you access a property of an object in Python?

• Using square brackets

• Using the dot notation

• Using parentheses

• Using curly braces

What is the difference between a method and a function in Python?

• Methods are defined outside classes

• Methods are functions defined inside classes

• Functions are defined inside classes

• There is no difference

What does the 'self' parameter represent in a class method?

• The class itself

• The module name

• The object instance

• The method name

How can you call a method on an object in Python?

• object.method()

• method:object()

• method(object)

• object:method()

What is the benefit of defining methods inside a class?

• To make methods inaccessible

• To make code less readable

• To keep data and methods together

• To increase code redundancy

How can you pass additional parameters to the __init__ method?

• By defining them in the class body

• By using a separate function

• By using global variables

• By adding them as parameters in the __init__ method

What happens when you create multiple objects from the same class?

• They share the same data

• They are independent with their own data

• They overwrite each other

• They cannot be created
