Python 3 Deep Dive: Mastering Advanced Object-Oriented Programming

True Python OOP is not about mimicking Java. It is about , composition over inheritance , and duck typing with guards .

def my_meta(name, bases, dct): dct['version'] = 1.0 return type(name, bases, dct) python 3 deep dive part 4 oop high quality

class IntegerValue: def __set_name__(self, owner, name): self.name = name def __set__(self, instance, value): if not isinstance(value, int): raise ValueError(f"self.name must be an integer") instance.__dict__[self.name] = value

Custom metaclasses intercept the creation of classes. This is highly useful for framework development, API enforcement, automatic registration, and validation at load time.

You cannot assign attributes to the object unless they are explicitly listed in __slots__ . strictly as an optimization tool when dealing with

rp = RegularPoint(); rp.x, rp.y = 1, 2 sp = SlottedPoint(); sp.x, sp.y = 1, 2

print(MyClass.version) # 1.0

Python resolves method lookups in multiple inheritance hierarchies using the C3 Linearization algorithm. def my_meta(name, bases, dct): dct['version'] = 1

: Includes multiple hands-on projects, such as building a bank account system and an inventory management model. : Provides fully annotated Jupyter Notebooks , lecture slides, and a comprehensive GitHub repository for all code examples. Prerequisites

: The exhaustive list of lectures (including theory vs. coding videos) is hosted on Udemy .

when you need dry, reusable validation across multiple class attributes.

, it is specifically designed for intermediate to advanced developers who want to master Python's object-oriented internals. Key Highlights of the Course Depth of Content : The course spans roughly 36.5 hours

Properties are the standard way to implement getters, setters, and deleters in Python, allowing you to wrap attribute access with logic without changing the public API.
