REST APIs with Flask and Python - Custom Error Classes

The video tutorial covers the creation and use of custom error classes in Python. It begins with setting up a simple book class with properties and methods, including a read function. The tutorial then addresses the issue of reading more pages than available by implementing error handling in the read method. A custom error class, 'TooManyPagesReadError', is created to provide specific error messages. The video concludes with best practices for creating custom error classes, emphasizing the importance of inheritance and naming for clarity.

What are the three properties defined in the Book class?

• Genre, Publisher, Year

• ISBN, Language, Edition

• Name, Page Count, Pages Read

• Title, Author, Pages

What issue arises when trying to read more pages than a book contains?

• The program crashes

• The book gets deleted

• It incorrectly reports more pages read than available

• The book title changes

What is the purpose of creating a custom error class in the context of the Book class?

• To add more properties to the Book class

• To change the book's title

• To handle specific errors like reading too many pages

• To increase the book's page count

Which built-in Python error class is used as a base for the custom error class?

• TypeError

• RuntimeError

• ValueError

• IndexError

What is a key benefit of using custom error classes?

• They make the code run faster

• They provide more specific error messages

• They reduce the number of lines of code

• They automatically fix errors

How can custom error classes improve user experience?

• By increasing the application's speed

• By reducing the application's size

• By making the application look more modern

• By providing detailed error messages

What should you do if you want to create a custom error class?

• Inherit from a built-in exception class

• Create a new programming language

• Use a different IDE

• Write the error class in a separate file
