Python 类型提示 pickable 参数

问：

我想与我的代码用户沟通，某些函数需要一个可选取的对象。下面是从任何项目详细信息中抽象出来的示例：

import pickle
from typing import Callable


def pickable():
    print("I am pickable!")


def get_non_pickable():
    # local functions are not pickable
    def not_pickable():
        print("I am NOT pickable!")

    return not_pickable


def pickle_func(func: Callable[[], None]):
    with open("data.pickle", "wb") as f:
        pickle.dump(func, f, pickle.HIGHEST_PROTOCOL)


# fine:
pickle_func(pickable)

# not fine: should show in my editor that I am passing a non-pickable item
pickle_func(get_non_pickable())

是否可以键入提示，表明函数中的函数参数必须是可选取的？理想情况下，应保留参数的现有类型提示。funcpickle_func
