REST APIs with Flask and Python - Magic Methods: __str__ and __repr__

The video tutorial explains two special methods in Python: __str__ and __repr__. These methods, known as magic methods, allow objects to be represented as strings. The __str__ method is used to provide a user-friendly string representation of an object, while the __repr__ method aims to provide an unambiguous string that can recreate the object. The tutorial demonstrates how to implement these methods in a Python class, using a 'Person' object as an example. It highlights the importance of these methods in making objects more informative and useful for both users and programmers.

What is the primary role of the __init__ method in Python?

• To initialize a new object with default values

• To convert an object to a string

• To print the object details

• To delete an object

Why does Python print a default string representation of an object?

• To ensure security

• To enhance performance

• Because objects cannot be directly printed

• To save memory

What is the main purpose of the __str__ method?

• To offer a user-friendly string representation of an object

• To initialize an object

• To provide a detailed technical description of an object

• To delete an object

How does the __str__ method affect the output when printing an object?

• It changes the object type

• It provides a custom string representation

• It initializes the object

• It deletes the object

What is the goal of the __repr__ method?

• To initialize an object

• To delete an object

• To offer an unambiguous representation for recreating the object

• To provide a user-friendly string representation

In what scenario is the __repr__ method particularly useful?

• When deleting objects

• When initializing objects

• When debugging or logging

• When printing objects for end-users

Which method is typically used by default when printing an object?

• __repr__

• __init__

• __del__

• __str__
