Python Dataclasses

Python Dataclasses are a lightweight Python way to define structured objects that mostly hold data. In Brevvie Python + AI — Section 2: Control Flow & The Treasure Hunt, @dataclass is used to model adventurers cleanly.

Why they matter

• reduce boilerplate for structured classes
• make fields explicit
• pair well with type hints
• help represent domain objects more clearly than ad hoc dicts

In the course

The Section 2 lesson uses dataclasses to contrast object attribute access (obj.attr) with dict key access (d['key']).
