Do union types actually exist in python?

Question

Since python is dynamically typed, of course we can do something like this:

def f(x):
    return 2 if x else \"s\"

But is this the way pyth

Answer 1

the type itself does not exist because Python is just a dynamically typed language, however, in newer Python versions, Union Type is an option for Type Hinting,

from typing import Union,TypeVar

T = TypeVar('T')
def f(x: T) -> Union[str, None]:
    if x:
        return "x"

you can use that to annotate your code, thus enabling IDE/Editor level syntax checking.
