Attributes are the data members of a class, while methods are the functions that belong to a class. In the example above, make , model , and year are attributes of the Car class, while honk is a method.

In this example, Car is a class that has three attributes: make , model , and year . The __init__ method is a special method that's called when an object is created from the class. It's used to initialize the attributes of the class. Python 3- Deep Dive -Part 4 - OOP-

In this example, Shape is an abstract class that defines the area method, which must be implemented by any subclass.

However, we aren't going to rehash the beginner's guide to class and def __init__ . This is a deep dive. We will explore Python’s OOP internals: the @dataclass decorator, descriptors, __slots__ , method resolution order (MRO), and abstract base classes (ABCs). The __init__ method is a special method that's

Here are some example use cases that demonstrate the concepts covered in this article:

class MessageSender(ABC): # Abstraction @abstractmethod def send(self, message: str) -> None: pass However, we aren't going to rehash the beginner's

class Sparrow(FlyingBird): def move(self): return self.fly(100) def fly(self, altitude: int): return f"Flying at altitude"

Most tutorials stop at the constructor. But in Python, object creation is a two-step process:
