This is an example of migrating a module to use type annotations, following the gradual migration strategy. Changes to `i18n.py`: - Add `from __future__ import annotations` - Add `from typing import Callable` import - Add type annotations for translation function and variables - Add type: ignore[no-redef] comment to suppress mypy warning about conditional definition of _ in try/except/else blocks Changes to pyproject.toml: - Add `ironicclient/common/i18n.py` to mypy files list for type checking Change-Id: Iffd9b5aff0530c2ddde0889cc31aa99e64b7f5a2 Signed-off-by: Karan Anand <anandkarancompsci@gmail.com>
