[issue31239] namedtuple comparison ignores types

2017-08-19 Thread R. David Murray
R. David Murray added the comment: This is by design: namedtuples are tuples in which you can access the elements by name. If you have a tuple with the same elements, but no name access, they should compare equal, because they are fundamentally tuples. The names are just a convenience.

Vlad Shcherbina added the comment: While we are at it, namedtuple inherits other operations that make no sense for fixed-length tuples: >>> Rectangle(width=1, height=2) * 3 (1, 2, 1, 2, 1, 2) >>> Rectangle(width=1, height=2) + Ellipse(x_axis=3, y_axis=4) (1, 2, 3, 4) But those are not so

New submission from Vlad Shcherbina: Toy example: >>> from collections import namedtuple >>> Rectangle = namedtuple('Rectangle', 'width height') >>> Ellipse = namedtuple('Ellipse', 'x_axis y_axis') >>> Rectangle(width=1, height=2) == Ellipse(x_axis=1, y_axis=2) True I understand this happens
