**Key Points**

- Define Python classes with the **`class` keyword**
- Add state to your classes with **class** and **instance attributes**
- Provide **behavior** to your classes with **methods**
- Use **inheritance** to build hierarchies of classes
- Provide **interfaces** with **abstract classes**
