Python class

A constructor is a special kind of method that Python calls when it instantiates an object using the definitions found in your class . Python relies on the constructor to perform tasks such as initializing (assigning values to) any instance variables that the object will need when it starts.16 Eki 2019

__init__() is not a constructor . We saw the self as the first parameter which is nothing but the object itself i.e object already exists. __init__() is called immediately after the object is created and is used to initialize it.

Advantages of Constructors when an object is created for a python class. The constructor function will be the first code segment to be initiated for execution, and this makes all initializations to happen as the first instance of work for the program .

The __new__() is a static method of the object class . When you create a new object by calling the class, Python calls the __new__() method to create the object first and then calls the __init__() method to initialize the object’s attributes.
