This kind of question is better asked on the main python-list, as this
one is about making suggestions for future changes.
What you've done there is create a type annotation (albeit a
meaningless one). On its own, that's not very useful, but there are
many great ways to use them:
@dataclass
class PackedItemData(ProtoBuf):
serial: bytes
quantity: int
equipped: int
mark: int
These annotations define the way that this structure is loaded and
saved in a file, but they don't actually give values to those
variables (which is why you still get the NameError). There's just a
record in the annotations dictionary saying "hey, mark is meant to be
an int", or in your case, "hey, a is meant to be a 3".
