Subject: [PATCH 03/69] [Exchange Oracle] Autofix ANN204:
 missing-return-type-special-method

Checks that "special" methods, like `__init__`, `__new__`, and `__call__`, have
return type annotations.

Type annotations are a good way to document the return types of functions. They also
help catch bugs, when used alongside a type checker, by ensuring that the types of
any returned values, and the types expected by callers, match expectation.

Note that type checkers often allow you to omit the return type annotation for
`__init__` methods, as long as at least one argument has a type annotation. To
opt in to this behavior, use the `mypy-init-return` setting in your `pyproject.toml`
or `ruff.toml` file:

```toml
[tool.ruff.lint.flake8-annotations]
mypy-init-return = true
```

```python
class Foo:
    def __init__(self, x: int):
        self.x = x
```

Use instead:
```python
class Foo:
    def __init__(self, x: int) -> None:
        self.x = x
```

Checks for membership tests using `not {element} in {collection}`.

Testing membership with `{element} not in {collection}` is more readable.

```python
Z = not X in Y
if not X.B in Y:

Use instead:
```python
Z = X not in Y
if X.B not in Y:
    pass

Subject: [PATCH 05/69] [Exchange Oracle] Autofix F541:
 f-string-missing-placeholders

Checks for f-strings that do not contain any placeholder expressions.

f-strings are a convenient way to format strings, but they are not
necessary if there are no placeholder expressions to format. In this
case, a regular string should be used instead, as an f-string without
placeholders can be confusing for readers, who may expect such a
placeholder to be present.

An f-string without any placeholders could also indicate that the
author forgot to add a placeholder expression.

```python
f"Hello, world!"
```

Use instead:
```python
"Hello, world!"
```

**Note:** to maintain compatibility with PyFlakes, this rule only flags
f-strings that are part of an implicit concatenation if _none_ of the
f-string segments contain placeholder expressions.

For example:

```python
(
    f"Hello,"
    f" {name}!"
)

(
    f"Hello,"
    f" World!"
)
```

See [#10885](https://github.com/astral-sh/ruff/issues/10885) for more.

Subject: [PATCH 06/69] [Exchange Oracle] Autofix F841: unused-variable

Checks for the presence of unused variables in function scopes.

A variable that is defined but not used is likely a mistake, and should
be removed to avoid confusion.

If a variable is intentionally defined-but-not-used, it should be
prefixed with an underscore, or some other value that adheres to the
[`lint.dummy-variable-rgx`] pattern.

Under [preview mode](https://docs.astral.sh/ruff/preview), this rule also
triggers on unused unpacked assignments (for example, `x, y = foo()`).

```python
def foo():
    x = 1
    y = 2
    return x
```

Use instead:
```python
def foo():
    x = 1
    return x
```

- `lint.dummy-variable-rgx`

Subject: [PATCH 07/69] [Exchange Oracle] Autofix RET501:
 unnecessary-return-none

Checks for the presence of a `return None` statement when `None` is the only
possible return value.

Python implicitly assumes `return None` if an explicit `return` value is
omitted. Therefore, explicitly returning `None` is redundant and should be
avoided when it is the only possible `return` value across all code paths
in a given function.

```python
def foo(bar):
    if not bar:
        return
    return None
```

Use instead:
```python
def foo(bar):
    if not bar:
        return
    return
```

for non-equality, it is more common to use `!=` than `==`.

`None` is the default value for `dict.get()`, so it is redundant to pass it

Subject: [PATCH 13/69] [Exchange Oracle] Autofix UP005:
 deprecated-unittest-alias

Checks for uses of deprecated methods from the `unittest` module.

The `unittest` module has deprecated aliases for some of its methods.
The aliases may be removed in future versions of Python. Instead,
use their non-deprecated counterparts.

```python
from unittest import TestCase

class SomeTest(TestCase):
    def test_something(self):
        self.assertEquals(1, 1)
```

Use instead:
```python
from unittest import TestCase

class SomeTest(TestCase):
    def test_something(self):
        self.assertEqual(1, 1)
```

Subject: [PATCH 14/69] [Exchange Oracle] Autofix UP006: non-pep585-annotation

Checks for the use of generics that can be replaced with standard library
variants based on [PEP 585].

[PEP 585] enabled collections in the Python standard library (like `list`)
to be used as generics directly, instead of importing analogous members
from the `typing` module (like `typing.List`).

When available, the [PEP 585] syntax should be used instead of importing
members from the `typing` module, as it's more concise and readable.
Importing those members from `typing` is considered deprecated as of [PEP
585].

This rule is enabled when targeting Python 3.9 or later (see:
[`target-version`]). By default, it's _also_ enabled for earlier Python
versions if `from __future__ import annotations` is present, as
`__future__` annotations are not evaluated at runtime. If your code relies
on runtime type annotations (either directly or via a library like
Pydantic), you can disable this behavior for Python versions prior to 3.9
by setting [`lint.pyupgrade.keep-runtime-typing`] to `true`.

```python
from typing import List

foo: List[int] = [1, 2, 3]
```

Use instead:
```python
foo: list[int] = [1, 2, 3]
```

This rule's fix is marked as unsafe, as it may lead to runtime errors when
alongside libraries that rely on runtime type annotations, like Pydantic,
on Python versions prior to Python 3.9.

- `target-version`
- `lint.pyupgrade.keep-runtime-typing`

[PEP 585]: https://peps.python.org/pep-0585/

Subject: [PATCH 15/69] [Exchange Oracle] Autofix UP007: non-pep604-annotation

Check for type annotations that can be rewritten based on [PEP 604] syntax.

[PEP 604] introduced a new syntax for union type annotations based on the
`|` operator. This syntax is more concise and readable than the previous
`typing.Union` and `typing.Optional` syntaxes.

This rule is enabled when targeting Python 3.10 or later (see:
[`target-version`]). By default, it's _also_ enabled for earlier Python
versions if `from __future__ import annotations` is present, as
`__future__` annotations are not evaluated at runtime. If your code relies
on runtime type annotations (either directly or via a library like
Pydantic), you can disable this behavior for Python versions prior to 3.10
by setting [`lint.pyupgrade.keep-runtime-typing`] to `true`.

```python
from typing import Union

foo: Union[int, str] = 1
```

Use instead:
```python
foo: int | str = 1
```

This rule's fix is marked as unsafe, as it may lead to runtime errors when
alongside libraries that rely on runtime type annotations, like Pydantic,
on Python versions prior to Python 3.10. It may also lead to runtime errors
in unusual and likely incorrect type annotations where the type does not
support the `|` operator.

- `target-version`
- `lint.pyupgrade.keep-runtime-typing`

[PEP 604]: https://peps.python.org/pep-0604/

Subject: [PATCH 16/69] [Exchange Oracle] Autofix UP032: f-string

Checks for `str.format` calls that can be replaced with f-strings.

f-strings are more readable and generally preferred over `str.format`
calls.

```python
"{}".format(foo)
```

Use instead:
```python
f"{foo}"
```

- [Python documentation: f-strings](https://docs.python.org/3/reference/lexical_analysis.html#f-strings)

Subject: [PATCH 17/69] [Exchange Oracle] Autofix UP035: deprecated-import

Checks for uses of deprecated imports based on the minimum supported
Python version.

Deprecated imports may be removed in future versions of Python, and
should be replaced with their new equivalents.

Note that, in some cases, it may be preferable to continue importing
members from `typing_extensions` even after they're added to the Python
standard library, as `typing_extensions` can backport bugfixes and
optimizations from later Python versions. This rule thus avoids flagging
imports from `typing_extensions` in such cases.

```python
from collections import Sequence
```

Use instead:
```python
from collections.abc import Sequence
```

Subject: [PATCH 18/69] [Exchange Oracle] Autofix UP037: quoted-annotation

Checks for the presence of unnecessary quotes in type annotations.

In Python, type annotations can be quoted to avoid forward references.

However, if `from __future__ import annotations` is present, Python
will always evaluate type annotations in a deferred manner, making
the quotes unnecessary.

Similarly, if the annotation is located in a typing-only context and
won't be evaluated by Python at runtime, the quotes will also be
considered unnecessary. For example, Python does not evaluate type
annotations on assignments in function bodies.

Given:

```python
from __future__ import annotations

def foo(bar: "Bar") -> "Bar": ...
```

Use instead:

```python
from __future__ import annotations

def foo(bar: Bar) -> Bar: ...
```

Given:

```python
def foo() -> None:
    bar: "Bar"
```

Use instead:

```python
def foo() -> None:
    bar: Bar
```

- [PEP 563](https://peps.python.org/pep-0563/)
- [Python documentation: `__future__`](https://docs.python.org/3/library/__future__.html#module-__future__)

Subject: [PATCH 19/69] [Exchange Oracle] Unsafe autofix ANN204:
 missing-return-type-special-method

Checks that "special" methods, like `__init__`, `__new__`, and `__call__`, have
return type annotations.

Type annotations are a good way to document the return types of functions. They also
help catch bugs, when used alongside a type checker, by ensuring that the types of
any returned values, and the types expected by callers, match expectation.

Note that type checkers often allow you to omit the return type annotation for
`__init__` methods, as long as at least one argument has a type annotation. To
opt in to this behavior, use the `mypy-init-return` setting in your `pyproject.toml`
or `ruff.toml` file:

```toml
[tool.ruff.lint.flake8-annotations]
mypy-init-return = true
```

```python
class Foo:
    def __init__(self, x: int):
        self.x = x
```

Use instead:
```python
class Foo:
    def __init__(self, x: int) -> None:
        self.x = x
```

Subject: [PATCH 22/69] [Exchange Oracle] Unsafe autofix B006:
 mutable-argument-default

Checks for uses of mutable objects as function argument defaults.

Function defaults are evaluated once, when the function is defined.

The same mutable object is then shared across all calls to the function.
If the object is modified, those modifications will persist across calls,
which can lead to unexpected behavior.

Instead, prefer to use immutable data structures, or take `None` as a
default, and initialize a new mutable object inside the function body
for each call.

Arguments with immutable type annotations will be ignored by this rule.
Types outside of the standard library can be marked as immutable with the
[`lint.flake8-bugbear.extend-immutable-calls`] configuration option.

Mutable argument defaults can be used intentionally to cache computation
results. Replacing the default with `None` or an immutable data structure
does not work for such usages. Instead, prefer the `@functools.lru_cache`
decorator from the standard library.

```python
def add_to_list(item, some_list=[]):
    some_list.append(item)
    return some_list

l1 = add_to_list(0)  # [0]
l2 = add_to_list(1)  # [0, 1]
```

Use instead:
```python
def add_to_list(item, some_list=None):
    if some_list is None:
        some_list = []
    some_list.append(item)
    return some_list

l1 = add_to_list(0)  # [0]
l2 = add_to_list(1)  # [1]
```

Checks for unused variables in loops (e.g., `for` and `while` statements).

Defining a variable in a loop statement that is never used can confuse
readers.

If the variable is intended to be unused (e.g., to facilitate
destructuring of a tuple or other object), prefix it with an underscore
to indicate the intent. Otherwise, remove the variable entirely.

Subject: [PATCH 24/69] [Exchange Oracle] Unsafe autofix B011: assert-false

Checks for uses of `assert False`.

Python removes `assert` statements when running in optimized mode
(`python -O`), making `assert False` an unreliable means of
raising an `AssertionError`.

Instead, raise an `AssertionError` directly.

```python
assert False
```

Use instead:
```python
raise AssertionError
```

This rule's fix is marked as unsafe, as changing an `assert` to a
`raise` will change the behavior of your program when running in
optimized mode (`python -O`).

Subject: [PATCH 25/69] [Exchange Oracle] Unsafe autofix C400:
 unnecessary-generator-list

Checks for unnecessary generators that can be rewritten as `list`
comprehensions (or with `list` directly).

It is unnecessary to use `list` around a generator expression, since
there are equivalent comprehensions for these types. Using a
comprehension is clearer and more idiomatic.

Further, if the comprehension can be removed entirely, as in the case of
`list(x for x in foo)`, it's better to use `list(foo)` directly, since it's
even more direct.

```python
list(f(x) for x in foo)
list(x for x in foo)
list((x for x in foo))
```

Use instead:
```python
[f(x) for x in foo]
list(foo)
list(foo)
```

This rule's fix is marked as unsafe, as it may occasionally drop comments
when rewriting the call. In most cases, though, comments will be preserved.

Subject: [PATCH 26/69] [Exchange Oracle] Unsafe autofix C401:
 unnecessary-generator-set

Checks for unnecessary generators that can be rewritten as `set`
comprehensions (or with `set` directly).

It is unnecessary to use `set` around a generator expression, since
there are equivalent comprehensions for these types. Using a
comprehension is clearer and more idiomatic.

Further, if the comprehension can be removed entirely, as in the case of
`set(x for x in foo)`, it's better to use `set(foo)` directly, since it's
even more direct.

```python
set(f(x) for x in foo)
set(x for x in foo)
```

Use instead:
```python
{f(x) for x in foo}
set(foo)
```

This rule's fix is marked as unsafe, as it may occasionally drop comments
when rewriting the call. In most cases, though, comments will be preserved.

Subject: [PATCH 27/69] [Exchange Oracle] Unsafe autofix C408:
 unnecessary-collection-call

Checks for unnecessary `dict`, `list` or `tuple` calls that can be
rewritten as empty literals.

It's unnecessary to call, e.g., `dict()` as opposed to using an empty
literal (`{}`). The former is slower because the name `dict` must be
looked up in the global scope in case it has been rebound.

```python
dict()
dict(a=1, b=2)
list()
tuple()
```

Use instead:
```python
{}
{"a": 1, "b": 2}
[]
()
```

This rule's fix is marked as unsafe, as it may occasionally drop comments
when rewriting the call. In most cases, though, comments will be preserved.

Subject: [PATCH 28/69] [Exchange Oracle] Unsafe autofix E731:
 lambda-assignment

Checks for lambda expressions which are assigned to a variable.

Per PEP 8, you should "Always use a def statement instead of an assignment
statement that binds a lambda expression directly to an identifier."

Using a `def` statement leads to better tracebacks, and the assignment
itself negates the primary benefit of using a `lambda` expression (i.e.,
that it can be embedded inside another expression).

```python
f = lambda x: 2 * x
```

Use instead:
```python
def f(x):
    return 2 * x
```

[PEP 8]: https://peps.python.org/pep-0008/#programming-recommendations

Subject: [PATCH 29/69] [Exchange Oracle] Unsafe autofix F841: unused-variable

Checks for the presence of unused variables in function scopes.

A variable that is defined but not used is likely a mistake, and should
be removed to avoid confusion.

If a variable is intentionally defined-but-not-used, it should be
prefixed with an underscore, or some other value that adheres to the
[`lint.dummy-variable-rgx`] pattern.

Under [preview mode](https://docs.astral.sh/ruff/preview), this rule also
triggers on unused unpacked assignments (for example, `x, y = foo()`).

```python
def foo():
    x = 1
    y = 2
    return x
```

Use instead:
```python
def foo():
    x = 1
    return x
```

- `lint.dummy-variable-rgx`

 static-join-to-f-string

Checks for `str.join` calls that can be replaced with f-strings.

f-strings are more readable and generally preferred over `str.join` calls.

```python
" ".join((foo, bar))
```

Use instead:
```python
f"{foo} {bar}"
```

Subject: [PATCH 31/69] [Exchange Oracle] Unsafe autofix PT009:
 pytest-unittest-assertion

Checks for uses of assertion methods from the `unittest` module.

To make use of `pytest`'s assertion rewriting, a regular `assert` statement
is preferred over `unittest`'s assertion methods.

```python
import unittest

class TestFoo(unittest.TestCase):
    def test_foo(self):
        self.assertEqual(a, b)
```

Use instead:
```python
import unittest

class TestFoo(unittest.TestCase):
    def test_foo(self):
        assert a == b
```

Subject: [PATCH 32/69] [Exchange Oracle] Unsafe autofix PT018:
 pytest-composite-assertion

Checks for assertions that combine multiple independent conditions.

Composite assertion statements are harder to debug upon failure, as the
failure message will not indicate which condition failed.

```python
def test_foo():
    assert something and something_else

def test_bar():
    assert not (something or something_else)
```

Use instead:
```python
def test_foo():
    assert something
    assert something_else

def test_bar():
    assert not something
    assert not something_else
```

Subject: [PATCH 33/69] [Exchange Oracle] Unsafe autofix PT027:
 pytest-unittest-raises-assertion

Checks for uses of exception-related assertion methods from the `unittest`
module.

To enforce the assertion style recommended by `pytest`, `pytest.raises` is
preferred over the exception-related assertion methods in `unittest`, like
`assertRaises`.

```python
import unittest

class TestFoo(unittest.TestCase):
    def test_foo(self):
        with self.assertRaises(ValueError):
            raise ValueError("foo")
```

Use instead:
```python
import unittest
import pytest

class TestFoo(unittest.TestCase):
    def test_foo(self):
        with pytest.raises(ValueError):
            raise ValueError("foo")
```

Subject: [PATCH 34/69] [Exchange Oracle] Unsafe autofix RET503:
 implicit-return

Checks for missing explicit `return` statements at the end of functions
that can return non-`None` values.

The lack of an explicit `return` statement at the end of a function that
can return non-`None` values can cause confusion. Python implicitly returns
`None` if no other return value is present. Adding an explicit
`return None` can make the code more readable by clarifying intent.

```python
def foo(bar):
    if not bar:
        return 1
```

Use instead:
```python
def foo(bar):
    if not bar:
        return 1
    return None
```

Subject: [PATCH 36/69] [Exchange Oracle] Unsafe autofix RUF013:
 implicit-optional

Checks for the use of implicit `Optional` in type annotations when the
default parameter value is `None`.

Implicit `Optional` is prohibited by [PEP 484]. It is confusing and
inconsistent with the rest of the type system.

It's recommended to use `Optional[T]` instead. For Python 3.10 and later,
you can also use `T | None`.

```python
def foo(arg: int = None):
    pass
```

Use instead:
```python
from typing import Optional

def foo(arg: Optional[int] = None):
    pass
```

Or, for Python 3.10 and later:
```python
def foo(arg: int | None = None):
    pass
```

If you want to use the `|` operator in Python 3.9 and earlier, you can
use future imports:
```python
from __future__ import annotations

def foo(arg: int | None = None):
    pass
```

Type aliases are not supported and could result in false negatives.
For example, the following code will not be flagged:
```python
Text = str | bytes

def foo(arg: Text = None):
    pass
```

- `target-version`

 duplicate-isinstance-call

Checks for multiple `isinstance` calls on the same target.

To check if an object is an instance of any one of multiple types
or classes, it is unnecessary to use multiple `isinstance` calls, as
the second argument of the `isinstance` built-in function accepts a
tuple of types and classes.

Using a single `isinstance` call implements the same behavior with more
concise code and clearer intent.

```python
if isinstance(obj, int) or isinstance(obj, float):
    pass
```

Use instead:
```python
if isinstance(obj, (int, float)):
    pass
```

 typing-only-first-party-import

Checks for first-party imports that are only used for type annotations, but
aren't defined in a type-checking block.

Unused imports add a performance overhead at runtime, and risk creating
import cycles. If an import is _only_ used in typing-only contexts, it can
instead be imported conditionally under an `if TYPE_CHECKING:` block to
minimize runtime overhead.

If [`lint.flake8-type-checking.quote-annotations`] is set to `true`,
annotations will be wrapped in quotes if doing so would enable the
corresponding import to be moved into an `if TYPE_CHECKING:` block.

If a class _requires_ that type annotations be available at runtime (as is
the case for Pydantic, SQLAlchemy, and other libraries), consider using
the [`lint.flake8-type-checking.runtime-evaluated-base-classes`] and
[`lint.flake8-type-checking.runtime-evaluated-decorators`] settings to mark them
as such.

```python
from __future__ import annotations

Subject: [PATCH 43/69] [Exchange Oracle] Unsafe autofix TRY201: verbose-raise

Checks for needless exception names in `raise` statements.

It's redundant to specify the exception name in a `raise` statement if the
exception is being re-raised.

```python
def foo():
    try:
        ...
    except ValueError as exc:
        raise exc
```

Use instead:
```python
def foo():
    try:
        ...
    except ValueError:
        raise
```

This rule's fix is marked as unsafe, as it doesn't properly handle bound
exceptions that are shadowed between the `except` and `raise` statements.

Subject: [PATCH 44/69] [Exchange Oracle] Unsafe autofix TRY400:
 error-instead-of-exception

Checks for uses of `logging.error` instead of `logging.exception` when
logging an exception.

`logging.exception` logs the exception and the traceback, while
`logging.error` only logs the exception. The former is more appropriate
when logging an exception, as the traceback is often useful for debugging.

```python
import logging

def func():
    try:
        raise NotImplementedError
    except NotImplementedError:
        logging.error("Exception occurred")
```

Use instead:
```python
import logging

def func():
    try:
        raise NotImplementedError
    except NotImplementedError:
        logging.exception("Exception occurred")
```

This rule's fix is marked as safe when run against `logging.error` calls,
but unsafe when marked against other logger-like calls (e.g.,
`logger.error`), since the rule is prone to false positives when detecting
logger-like calls outside of the `logging` module.

Subject: [PATCH 45/69] [Exchange Oracle] Unsafe autofix UP031:
 printf-string-formatting

Checks for `printf`-style string formatting, and offers to replace it with
`str.format` calls.

`printf`-style string formatting has a number of quirks, and leads to less
readable code than using `str.format` calls or f-strings. In general, prefer
the newer `str.format` and f-strings constructs over `printf`-style string
formatting.

```python
"%s, %s" % ("Hello", "World")  # "Hello, World"
```

Use instead:

```python
"{}, {}".format("Hello", "World")  # "Hello, World"
```

```python
f"{'Hello'}, {'World'}"  # "Hello, World"
```

In cases where the format string contains a single generic format specifier
(e.g. `%s`), and the right-hand side is an ambiguous expression,
we cannot offer a safe fix.

For example, given:

```python
"%s" % val
```

`val` could be a single-element tuple, _or_ a single value (not
contained in a tuple). Both of these would resolve to the same
formatted string when using `printf`-style formatting, but
resolve differently when using f-strings:

```python
val = 1
print("%s" % val)  # "1"
print("{}".format(val))  # "1"

val = (1,)
print("%s" % val)  # "1"
print("{}".format(val))  # "(1,)"
```

Subject: [PATCH 46/69] [Exchange Oracle] Unsafe autofix SIM300:
 yoda-conditions

Checks for conditions that position a constant on the left-hand side of the
comparison operator, rather than the right-hand side.

These conditions (sometimes referred to as "Yoda conditions") are less
readable than conditions that place the variable on the left-hand side of
the comparison operator.

In some languages, Yoda conditions are used to prevent accidental
assignment in conditions (i.e., accidental uses of the `=` operator,
instead of the `==` operator). However, Python does not allow assignments
in conditions unless using the `:=` operator, so Yoda conditions provide
no benefit in this regard.

```python
if "Foo" == foo:
    ...
```

Use instead:
```python
if foo == "Foo":
    ...
```

Subject: [PATCH 47/69] [Exchange Oracle] Autofix UP032: f-string

Checks for `str.format` calls that can be replaced with f-strings.

f-strings are more readable and generally preferred over `str.format`
calls.

```python
"{}".format(foo)
```

Use instead:
```python
f"{foo}"
```

Subject: [PATCH 48/69] [Exchange Oracle] Autofix UP038: non-pep604-isinstance

Checks for uses of `isinstance` and `issubclass` that take a tuple
of types for comparison.

Since Python 3.10, `isinstance` and `issubclass` can be passed a
`|`-separated union of types, which is consistent
with the union operator introduced in [PEP 604].

Note that this results in slower code. Ignore this rule if the
performance of an `isinstance` or `issubclass` check is a
concern, e.g., in a hot loop.

```python
isinstance(x, (int, float))
```

Use instead:
```python
isinstance(x, int | float)
```

- `target-version`

- [Python documentation: `isinstance`](https://docs.python.org/3/library/functions.html#isinstance)
- [Python documentation: `issubclass`](https://docs.python.org/3/library/functions.html#issubclass)
