What is the __ init __ in Python?
“__init__” is a reseved method in python classes. It is called as a constructor in object oriented terminology. This method is called when an object is created from a class and it allows the class to initialize the attributes of the class.
Does a Python class need a constructor?
Class constructors are a fundamental part of object-oriented programming in Python. They allow you to create and properly initialize objects of a given class, making those objects ready to use.
What is declaration and initialization in Python?
