unused-private-typed-dict (PYI049)

Derived from the flake8-pyi linter.

What it does

Checks for the presence of unused private typing.TypedDict definitions.

Why is this bad?

A private typing.TypedDict that is defined but not used is likely a mistake. It should either be used, made public, or removed to avoid confusion.

Example

import typing

class _UnusedPrivateTypedDict(typing.TypedDict):
    foo: list[int]

Use instead:

import typing

class _UsedPrivateTypedDict(typing.TypedDict):
    foo: set[str]

def func(arg: _UsedPrivateTypedDict) -> _UsedPrivateTypedDict: ...
