Ruff 无法捕获函数的未定义参数

Question

我不确定即使 ruff 的工作是捕获函数的未定义参数，但是有没有一个工具可以做到这一点？或者是否有我缺少添加的 ruff 配置，以便 ruff 可以做到这一点？

from typing import Optional


def my_func(bar: int, baz: int, foo: Optional[int] = None) -> int:
    if foo:
        return foo + bar + baz
    else:
        return bar + baz


my_func(foo=1, bar=2, baz=3)
my_func(bar=2, baz=3)
my_func(f=1, bar=2, baz=3) # this should have been caught by ruff, but isn't and I'm

Answer 1

Ruff 目前不支持此功能。引用Ruff常见问题解答：

Pylint 实现了许多 Ruff 没有的规则，反之亦然。例如，Pylint 比 Ruff 进行更多类型推断（例如，Pylint 可以验证函数调用中参数的数量）。因此，Ruff 并不是 Pylint 的“纯粹”替代品（反之亦然），因为它们执行不同的规则集。

尽管存在这些差异，许多用户已成功从 Pylint 切换到 Ruff，尤其是那些将 Ruff 与 类型检查器一起使用的用户，它可以涵盖 Pylint 提供的一些功能。
