Lecture 9 – Python Inheritance, Class & Static Methods

Lecture 9 wraps up our Python foundation with the last piece of Object-Oriented Programming: method types and inheritance. This is the final Python-only class before we move into the Generative AI portion of the course! What we cover in this lecture: The 3 types of methods in a Python class: Instance methods — the standard self-based methods you've already been using Class methods — using the cls keyword and the @classmethod decorator to work with class-level variables Static methods — helper functions inside a class that use neither self nor cls A quick intro to decorators (@classmethod, @staticmethod) — what that @something above a function actually means Inheritance — how a child class can inherit all properties and behavior from a parent class (Animal → Dog, Animal → Tiger examples) Creating a constructor inside a child class and using super().__init__() to reuse the parent class's initialization logic instead of rewriting it Adding child-class-specific attributes and methods on top of inherited ones A realistic look at where inheritance shows up in practice — including AI-generated code (e.g., when an LLM writes parent/child class structures for you) Interview reality check: OOP concepts are rarely asked directly, but loops remain the most common coding interview topic What's next: Python is officially complete! From the next class onward, the course moves fully into Generative AI — prompt engineering, LLM APIs, and beyond. Who this is for: Beginners following the structured Python-for-GenAI path — Lecture 8 (Classes & Objects) is the direct prerequisite for this one.
