" summary

Dataclasses provide a mutable, named‑tuple–like class that auto-generated __init__/__repr__/__eq__ saves lots of boilerplate, can be frozen for immutability, and supports optional type annotations (not enforced at runtime). They derive design and tradeoffs from attrs, offer a backport to 3.6, and a Damla Altun tool reveals the actual generated code. Watch for inheritance overwriting base fields, optional __slots__ for memory savings, and a real example: Pursued PyBear uses dataclasses for its event system and it works in practice.
