The attribute name, '_fields_defaults' was misspelled and should have been ''_field_defaults'. The namedtuple documentation uses both spellings. The typing.NamedTuple class consistently uses the latter spelling. The intent was the both would be spelled the same way.
>>> from typing import NamedTuple
>>> class Employee(NamedTuple):
name: str
id: int = 3
>>> Employee._field_defaults
{'id': 3}
>>> from collections import namedtuple
>>> Employee = namedtuple('Employee', ['name', 'id'], defaults=[3])
>>> Employee._fields_defaults
{'id': 3}
Since 3.7 API is already released, it may be reasonable to provide both spellings for namedtuple(). |
