[FIXED] Typing unused arguments

Issue

I have a function that has to take two arguments, like:

def f(first_arg: int, unused_arg) -> int:
    first_arg += 1
    return first_arg

I want to type my function, what should be the type of unused_arg ? From this question I guess None could be used.

For context, I'm using lax.scan from jax which needs a function with two arguments even when the second one is unused.

Solution

You can use Any?

from typing import Any

def f(first_arg: int, unused_arg: Any) -> int:
    ...
