Odoo models are Python classes — this lesson is the direct on-ramp to the framework.

Key topics

• Class vs instance; __init__ and instance attributes; class attributes and shared state.
• Instance methods, @classmethod, @staticmethod; self explained.
• Inheritance: extending and overriding methods, super(), multiple inheritance basics.
• Encapsulation conventions (public, _protected, __private); @property.
• Dunder methods: __str__, __repr__, __eq__, __len__, __getitem__ — how objects plug into Python syntax.

Exercise / deliverable

Model a mini LMS: a Course class (title, lessons list, add/remove lesson, duration_hours property) and an inherited PublishedCourse that adds publish state and overrides __str__.
