The Python default constructor is a simple constructor which doesn’t accept any arguments . Its definition has only one argument which is a reference to the instance being constructed.23 Eyl 2021

The __init__ method is similar to constructors in C++ and Java . Constructors are used to initialize the object’s state. The task of constructors is to initialize(assign values) to the data members of the class when an object of class is created.

This is because there is a default constructor implicitly injected by python during program compilation, this is an empty default constructor that looks like this: def __init__(self): # no body, does nothing. In this case, python does not create a constructor in our program .

In Python the __init__() method is called the constructor and is always called when an object is created. Types of constructors : default constructor: The default constructor is a simple constructor which doesn’t accept any arguments .10 Ağu 2021

The body of the constructor is defined inside the curly brackets { } after the parameter list. In the constructor example above the constructor has no operations inside the constructor body. It is said to be an “empty” constructor .

An empty __init__ will show folks, who read your code, that an empty object was OK when you wrote the code . You will have a place to put non-default initialization code when you need it.
