Abstract classes and interfaces are used to define a blueprint for other classes to follow. An abstract class is a class that can't be instantiated on its own and is meant to be inherited by other classes.

In , we will deep dive into Concurrency: Threads vs. Async vs. Multiprocessing.

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

Now, my_car is an object that has its own set of attributes and methods.

This is an excellent topic. is the cornerstone of maintainable, scalable Object-Oriented Programming. In the context of Python 3: Deep Dive (Part 4) , we move beyond basic syntax into how these principles interact with Python’s dynamic nature, descriptors, metaclasses, and Abstract Base Classes (ABCs). class Sparrow(FlyingBird): def move(self): return self
