unassigned-special-variable-in-stub (PYI035)

Added in v0.0.271 · Related issues · View source

Derived from the flake8-pyi linter.

What it does

Checks that __all__, __match_args__, and __slots__ variables are assigned to values when defined in stub files.

Why is this bad?

Special variables like __all__ have the same semantics in stub files as they do in Python modules, and so should be consistent with their runtime counterparts.

Example

__all__: list[str]

Use instead:

__all__: list[str] = ["foo", "bar"]
