This method is commonly mistaken for a constructor, but in Python, the actual constructor is the __new__ method, which is responsible for creating an instance.

Think of a class as a blueprint and the class object as a live, importable thing; when Python executes your class definition, it also wires in __init__() so instances can be configured cleanly. It doesn’t return a value like traditional functions. Instead, it prepares the object for use and binds the provided arguments to instance variables. ... This example highlights a basic init Python structure used to initialize an object with attributes.

Here is an example: **Code:** ```Python class ParentClass: def __init__(self): print("Parent Class") class Child(ParentC

November 15, 2024 - In Python, two special methods, __new__() and __init__(), play a crucial role in object creation and initialization. While both methods are related to how objects are constructed, they serve distinct purposes.
