Deep Learning - Computer Vision for Beginners Using PyTorch - Classes in Python

The video tutorial introduces Object-Oriented Programming (OOP) in Python, focusing on classes and objects. It explains how to create a class using the 'class' keyword, define attributes, and instantiate objects. The tutorial also covers methods within classes, emphasizing the importance of the 'self' parameter. Additionally, it introduces the special 'init' method for initializing objects. The tutorial concludes with a summary and a preview of a mini-project to apply the learned concepts.

What is the primary purpose of a class in Python?

• To execute code

• To store data

• To serve as a blueprint for creating objects

• To define variables

Which keyword is used to define a class in Python?

• object

• class

• def

• new

What is an attribute in the context of a Python class?

• A keyword to define a class

• A method to create objects

• A variable inside a class

• A function inside a class

How do you create an object from a class in Python?

• By using the 'new' keyword

• By defining a function

• By calling the class name with parentheses

• By using the 'create' keyword

How can you access an attribute of a class using an object?

• object.attribute

• class.attribute

• attribute.object

• attribute.class

What is the purpose of the 'self' parameter in class methods?

• To refer to the class itself

• To refer to the module

• To refer to the object instance

• To refer to the function

What is a common error when accessing class attributes inside a method?

• Using 'class' to access attributes

• Not using 'self' to access attributes

• Using 'object' to access attributes

• Using 'self' to access attributes

What is the '__init__' method used for in a Python class?

• To define class attributes

• To delete objects

• To initialize object attributes

• To create new methods

What happens if you do not provide the required arguments to the '__init__' method?

• The object is created without attributes

• An error is raised

• The class is not defined

• The object is created with default values

Which of the following is true about the '__init__' method?

• It is optional and can be omitted

• It cannot take any parameters

• It is automatically called when an object is created

• It must be called manually
