-# unused-import (F401)
-
-Derived from the **Pyflakes** linter.
-
-Fix is sometimes available.
-
-## What it does
-Checks for unused imports.
-
-## Why is this bad?
-Unused imports add a performance overhead at runtime, and risk creating
-import cycles. They also increase the cognitive load of reading the code.
-
-If an import statement is used to check for the availability or existence
-of a module, consider using `importlib.util.find_spec` instead.
-
-If an import statement is used to re-export a symbol as part of a module's
-public interface, consider using a "redundant" import alias, which
-instructs Ruff (and other tools) to respect the re-export, and avoid
-marking it as unused, as in:
-
-```python
-from module import member as member
-```
-
-Alternatively, you can use `__all__` to declare a symbol as part of the module's
-interface, as in:
-
-```python
-# __init__.py
-import some_module
-
-__all__ = ["some_module"]
-```
-
-## Preview
-When [preview] is enabled (and certain simplifying assumptions
-are met), we analyze all import statements for a given module
-when determining whether an import is used, rather than simply
-the last of these statements. This can result in both different and
-more import statements being marked as unused.
-
-For example, if a module consists of
-
-```python
-import a
-import a.b
-```
-
-then both statements are marked as unused under [preview], whereas
-only the second is marked as unused under stable behavior.
-
-As another example, if a module consists of
-
-```python
-import a.b
-import a
-
-a.b.foo()
-```
-
-then a diagnostic will only be emitted for the first line under [preview],
-whereas a diagnostic would only be emitted for the second line under
-stable behavior.
-
-Note that this behavior is somewhat subjective and is designed
-to conform to the developer's intuition rather than Python's actual
-execution. To wit, the statement `import a.b` automatically executes
-`import a`, so in some sense `import a` is _always_ redundant
-in the presence of `import a.b`.
-
-
-## Fix safety
-
-Fixes to remove unused imports are safe, except in `__init__.py` files.
-
-Applying fixes to `__init__.py` files is currently in preview. The fix offered depends on the
-type of the unused import. Ruff will suggest a safe fix to export first-party imports with
-either a redundant alias or, if already present in the file, an `__all__` entry. If multiple
-`__all__` declarations are present, Ruff will not offer a fix. Ruff will suggest an unsafe fix
-to remove third-party and standard library imports -- the fix is unsafe because the module's
-interface changes.
-
-See [this FAQ section](https://docs.astral.sh/ruff/faq/#how-does-ruff-determine-which-of-my-imports-are-first-party-third-party-etc)
-for more details on how Ruff
-determines whether an import is first or third-party.
-
-## Example
-
-```python
-import numpy as np  # unused import
-
-
-def area(radius):
-    return 3.14 * radius**2
-```
-
-Use instead:
-
-```python
-def area(radius):
-    return 3.14 * radius**2
-```
-
-To check the availability of a module, use `importlib.util.find_spec`:
-
-```python
-from importlib.util import find_spec
-
-if find_spec("numpy") is not None:
-    print("numpy is installed")
-else:
-    print("numpy is not installed")
-```
-
-## Options
-- `lint.ignore-init-module-imports`
-- `lint.pyflakes.allowed-unused-imports`
-
-## References
-- [Python documentation: `import`](https://docs.python.org/3/reference/simple_stmts.html#the-import-statement)
