Chapter 10: Problem 7

What is the purpose of the \(_{-}\) init \(_{-}\), method? When does it execute?

Short Answer

Expert verified
The `__init__` method is a special method in Python known as a constructor. Its purpose is to initialize the object's attributes and perform any necessary setup when creating an object from a class. The `__init__` method is automatically called every time a new object is created from a class, ensuring that all required properties and resources are set up before working with the object.

Step by step solution

01

Define the __init__ method

The `__init__` method is a special method in Python, known as a constructor. It is used to initialize the object's attributes and perform any necessary setup when creating an object from a class.
02

Explain the purpose of the __init__ method

The purpose of the `__init__` method is to: 1. Set default values for object attributes and properties. 2. Allocate resources or perform any setup required for the object's functionality. 3. Establish any relationships between the object and other objects. The `__init__` method is essential for initializing and preparing an object for use, as it allows you to ensure that all required properties and resources are set up before working with the object.
03

Describe when the __init__ method is executed

The `__init__` method is automatically called every time a new object is created from a class. This means that when you create an instance of a class, Python will first call the `__init__` method to set up the object and then return the newly created instance. For example, consider the following code: ```python class MyClass: def __init__(self): print("Init method called") obj = MyClass() ``` When the object `obj` is created, the `__init__` method is automatically called, and "Init method called" will be printed to the console.
