Chapter 11: Problem 7

What is the purpose of the _ _init_ _ method? When does it execute?

Short Answer

Expert verified
Answer: The "__init__" method, also known as the constructor, is a special method in Python's OOP used to initialize the attributes of an object with their default or initial values. It is executed immediately after a new instance of a class is created.

Step by step solution

01

Purpose of __init__ method

The "__init__" method in Python is a special method also called the constructor, which gets called automatically whenever a new instance of a class is created. It is used to initialize the attributes of an object with their default or initial values.
02

When the __init__ method is executed

The "__init__" method is executed immediately after an object is created. When a new object is created from a class, the constructor of that class is called automatically, initializing the object with default or specified values.
03

Example

Let's consider a Python class as an example to demonstrate the execution of the "__init__" method. ```python class Student: def __init__(self, name, age): self.name = name self.age = age def print_student_details(self): print("Name: ", self.name) print("Age: ", self.age) # Creating a new Student object student1 = Student("John Doe", 17) # Printing student details using the print_student_details method student1.print_student_details() ``` In this example, when the 'student1' object is created, the "__init__" method is called immediately, initializing the object's 'name' attribute with "John Doe" and the 'age' attribute with 17.
