What is the role of a class constructor in Python?	In Python, a class constructor is a special method used to initialize new objects. It is defined using the `__init__` method. When a new instance of a class is created, the `__init__` method is automatically called to set up the initial state of the object. This method can take parameters, besides `self`, which is a re...	In Python, a class constructor is a special method that is called when an object (an instance of the class) is created.
