Which answer is correct?

Use a `@dataclass`. It gives you type hints, default values, `__init__`, `__repr__`, `__eq__` for free, and your IDE can autocomplete field names: ``` @dataclass class User: name: str email: str age: int ```

Use a `NamedTuple`. It's immutable, lighter weight, and you can still access fields by name.

Use a dict. It's the simplest, most flexible option: `user = {"name": "Alice", "email": "a@b.com", "age": 30}`.
