But Python doesn't have pointers and getattr, settatr can be adjusted to work with private members.
Not really, this is explicitly mentioned on the docs. Here's an example:
from dataclasses import dataclass @dataclass(frozen=True) ... class Example: ... field: str ... e1 = Example('string') e1.field 'string' e1.field = 'Something' Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<string>", line 4, in __setattr__ dataclasses.FrozenInstanceError: cannot assign to field 'field' e1.__setattr__('field', 'Something') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<string>", line 4, in __setattr__ dataclasses.FrozenInstanceError: cannot assign to field 'field' object.__setattr__(e1, 'field', 'Something') e1.field 'Something'
"private" member are just a convention, always. No reflection or pointer manipulation is necessary to change them, let alone just reading. "@property", "getattr"/"setattr", "@cached_property" solves all problems that Java introduces with worthless getters and setters.
