About Python Dataclasses
Python dataclasses (introduced in Python 3.7) generate boilerplate like __init__, __repr__, and __eq__ automatically from type-annotated class attributes. They are a clean, standard-library way to model structured data such as parsed JSON.
This tool infers types from your sample: strings become str, whole numbers int, decimals float, booleans bool, nulls Optional, arrays List, and nested objects become their own dataclass. JSON keys that are not valid Python identifiers are renamed, with the original key noted in a comment.
