The task of constructors is to initialize(assign values) to the data members of the class when an object of the class is created. In Python the __init__() method is called the constructor and is always called when an object is created.
Class constructors internally trigger Python’s instantiation process, which runs through two main steps: instance creation and instance initialization. If you want to dive deeper into how Python internally constructs objects and learn how to customize the process, then this tutorial is for you.
Python classes provide all the standard features of Object Oriented Programming: the class inheritance mechanism allows multiple base classes, a derived class can override any methods of its base class or classes, and a method can call the method of a base class with the same name.
To create a constructor in Python, we need to define a special kind of magic method called __init__() inside our class. By default, this method takes one argument known as self. Self takes the address of the object as its argument and it is automatically provided by Python.
The constructor is a method that is called when an object is created. This method is defined in the class and can be used to initialize basic variables. If you create four objects, the class constructor is called four times.
A class constructor in Python is a special method that is executed when an object of a class is instantiated. It is used to initialize the attributes of the class. The constructor method in Python is called __init__() and it is defined within the class.

What is Constructor in Python? In object-oriented programming, A constructor is a special method used to create and initialize an object of a class. This method is defined in the class. The constructor is executed automatically at the time of object creation.
In this video course, you'll learn how class constructors work in Python. You'll also explore Python's instantiation process, which has two main steps: instance creation and instance initialization.
A constructor is a function that is called automatically when an object is created. A constructor can optionally accept arguments as well, just like a regular function. The default constructor. When creating an object from a class, it looks like we are calling a function: car = Car()
