Что читается лучше на ваш взгляд? @dataclass(init=False) class Subscription:

queue_name: str
callback: SubscriptionCallback
prefetch_size: int = 0
prefetch_count: int = 0

def __init__(
self,
queue: Union[Queue, str],
callback: SubscriptionCallback,
prefetch_size: int,
prefetch_count: int,
):
if isinstance(queue, Queue):
self.queue_name = queue.name
else:
self.queue_name = queue
self.callback = callback
self.prefetch_size = prefetch_size
self.prefetch_count = prefetch_count

ИЛИ

@dataclass
class Subscription:
queue: InitVar[Union[Queue, str]]

queue_name: Union[Queue, str] = field(init=False)
callback: SubscriptionCallback
prefetch_size: int = 0
prefetch_count: int = 0

def __post_init__(self, queue: Union[Queue, str]):
if isinstance(queue, Queue):
self.queue_name = queue.name
else:
self.queue_name = queue
