Nick Coghlan added the comment:
So that they can be returned from an API without breaking backwards
compatibility, named tuples are intentionally equivalent to the corresponding
ordinary tuple:
>>> from collections import namedtuple
>>> Pair = namedtuple("Pair", "x y")
>>> Pair(1, 2) == (1, 2)
True
Transitivity thus requires that two named tuples with different field names
also compare equal with each other:
>>> Pair2 = namedtuple("Pair2", "a b")
>>> Pair(1, 2) == (1, 2) == Pair2(1, 2)
True
>>> Pair(1, 2) == Pair2(1, 2)
True
So the field names on named tuples are just an access mechanism - they aren't
part of the value of the instances.
