Unused import (Python)
Part of Code Quality & Syntax, which counts for 20% of the overall score. When this check fires it deducts 2 points from that category, once per scan, no matter how many places it turns up.
What it detects
An imported name is never referenced elsewhere in the file (AST-based check).
Why it matters
Unused imports slow startup, keep phantom entries alive in requirements files long after the last real use, and can even change behavior when the imported module runs side effects at import time. They also mislead readers about what the module actually depends on.
How to fix it
Remove them with Ruff (rule F401, autofixable via ruff check --fix) or autoflake. Watch for imports kept for side effects or re-export: mark deliberate re-exports with __all__ or the "from x import y as y" form so tools know they are intentional.
