Is it possible to type hint a lambda function?

Question

Currently, in Python, a function\'s parameters and return types can be type hinted as follows:

def func(var1: str, var2: str) -> int:
    return var1.inde         


        

Answer 1

Since Python 3.6, you can (see PEP 526):

from typing import Callable
is_even: Callable[[int], bool] = lambda x: (x % 2 == 0)
