Python for AI Engineers, Part 2

The object-oriented core most real Python codebases — and most AI agent frameworks — are built on: classes and inheritance, abstract interfaces, dunder methods, dataclasses, typing, and how dependency injection actually looks without a container.

What's inside:

• Classes, Objects & __init__

• Instance Attributes vs Class Attributes

• Inheritance, Composition & Polymorphism

• Abstract Base Classes

• staticmethod, classmethod & Properties

• Magic Methods

• Dataclasses

• Type Hints, Generics & Protocol

• Dependency Injection

Every section follows the same shape: a mental-model card anchoring the new idea to something you already know, a small story with real numbers, a Your Turn you attempt yourself, then the full solution and why it works.

22 pages. Real code for every fix. No filler.
