collections-named-tuple (PYI024)

Derived from the flake8-pyi linter.

What it does

Checks for uses of collections.namedtuple in stub files.

Why is this bad?

typing.NamedTuple is the "typed version" of collections.namedtuple.

The class generated by subclassing typing.NamedTuple is equivalent to collections.namedtuple, with the exception that typing.NamedTuple includes an __annotations__ attribute, which allows type checkers to infer the types of the fields.

Example

from collections import namedtuple


person = namedtuple("Person", ["name", "age"])

Use instead:

from typing import NamedTuple


class Person(NamedTuple):
    name: str
    age: int
