Dan Parizher	f052bd644c	[`flake8-simplify`] Fix truthiness assumption for non-iterable arguments in tuple/list/set calls (`SIM222`, `SIM223`) (#21479) ... ## Summary Fixes false positives in SIM222 and SIM223 where truthiness was incorrectly assumed for `tuple(x)`, `list(x)`, `set(x)` when `x` is not iterable. Fixes #21473. ## Problem `Truthiness::from_expr` recursively called itself on arguments to iterable initializers (`tuple`, `list`, `set`) without checking if the argument is iterable, causing false positives for cases like `tuple(0) or True` and `tuple("") or True`. ## Approach Added `is_definitely_not_iterable` helper and updated `Truthiness::from_expr` to return `Unknown` for non-iterable arguments (numbers, booleans, None) and string literals when called with iterable initializers, preventing incorrect truthiness assumptions. ## Test Plan Added test cases to `SIM222.py` and `SIM223.py` for `tuple("")`, `tuple(0)`, `tuple(1)`, `tuple(False)`, and `tuple(None)` with `or True` and `and False` patterns. --------- Co-authored-by: Brent Westbrook <brentrwestbrook@gmail.com>	2025-12-01 16:57:51 -05:00
