In Python 3.5, how can I specify a function as a t

Question

What is the appropriate type hint to specify that a variable should be a function (the equivalent of a delegate, Func<T> or Action in C#)?

Is it also possible to specify the function argument types in a generic fashion as well (for example Func<int, int>)?

I cannot find any relevant details in the documentation.

Answer 1

According to the docs, you can use Callable, imported from typing.

You can view more details in PEP 0484.
