pythonImmutable Slot Dataclasses: The Best Way to Model Python Configuration Objects
When configuration values should never change after creation, frozen dataclasses with slots give you immutability, memory efficiency, and clear validation—all without boilerplate. Learn how to use them safely and what trade‑offs to watch for.
Python Dataclasses: Using __post_init__ for Validation and Computed Fields
Use @dataclass with __post_init__ to validate inputs and compute derived fields after initialization. Learn how to enforce invariants, handle mutable defaults, work with frozen dataclasses, and avoid common pitfalls like shared mutable state and inheritance issues.
Using Frozen, Slotted Dataclasses for Internal Service Messages in Python
An architecture note on using @dataclass(frozen=True, slots=True) as a minimal typed container for internal service messages: requirements, boundary validation, checks, and failure modes.
