Function asdict

Lib/dataclasses.py:1476–1497

Return the fields of a dataclass instance as a new dictionary mapping field names to field values. Example usage:: @dataclass class C: x: int y: int c = C(1, 2) assert asdict(c) == {'x': 1, 'y': 2} If given, 'dict_factory' will be used inst

    tuples, lists, and dicts. Other objects are copied with 'copy.deepcopy()'.
