New submission from Alex DeLorenzo <alex.delore...@gmail.com>:
Example:
from typing import NamedTuple
from dataclasses import dataclass, asdict
class NamedTupleAttribute(NamedTuple):
example: bool = True
@dataclass
class Data:
attr1: bool
attr2: NamedTupleAttribute
data = Data(True, NamedTupleAttribute(example=True))
namedtuple_attr = asdict(data)['attr2']
print(type(namedtuple_attr.example))
>>> generator
One would expect that the printed type would be of type bool.
