Hello, In my repository: https://github.com/LLyaudet/python-repeatable-iterable/blob/main/src/python_repeatable_iterable/__init__.py I have the following imports: ```python3 from typing import Iterable, Iterator, TypeVar, cast from _collections_abc import dict_items, dict_keys, dict_values from python_none_objects import NoneIterable ``` But isort does not recognize that ```python3 from _collections_abc import dict_items, dict_keys, dict_values ``` is part of the standard library and regroup it like that: ```python3 from typing import Iterable, Iterator, TypeVar, cast from _collections_abc import dict_items, dict_keys, dict_values from python_none_objects import NoneIterable ``` Best regards, Laurent Lyaudet
