late-future-import (F404)

Derived from the Pyflakes linter.

What it does

Checks for __future__ imports that are not located at the beginning of a file.

Why is this bad?

Imports from __future__ must be placed the beginning of the file, before any other statements (apart from docstrings). The use of __future__ imports elsewhere is invalid and will result in a SyntaxError.

Example

from pathlib import Path

from __future__ import annotations

Use instead:

from __future__ import annotations

from pathlib import Path
