我下面的功能foo， 其中有：
- 具有已知类型的一个位置 arg
- 之后有可变数量的位置参数和关键字参数
from typing import Callable
def foo(bar: str, *args, **kwargs) -> None:
"""Some function with one positional arg and then *args and **kwargs."""
foo_: Callable[[str, ...], None] = foo # error: Unexpected '...'
我如何输入提示？
现在，mypy==0.812抛出错误：error: Unexpected '...' [misc]
我可能会为此使用协议。它们通常比 Callables 更灵活一些。它看起来像这样
from typing import Protocol
class BarFunc(Protocol):
def __call__(fakeself, bar: str, *args, **kwargs) -> None:
# fakeself gets swallowed by the class method binding logic
# so this will match functions that have bar and the free arguments.
...
def foo(bar: str, *args, **kwargs) -> None:
"""Some function with one positional arg and then *args and **kwargs."""
foo_: BarFunc = foo
