How are array typehints declared in Python? [duplicate]

Question

Given this function:

def array_returner():
    return ["hello", "there"]

How would I typehint that this function returns an array of strings, without importing List (and using the List[str] syntax)?

Answer 1

Like this

from typing import List
def array_returner() -> List[str]:
    pass

Since python3.9

def array_returner() -> list[str]:
    pass

Answer 2

This is what you're looking for:

from typing import List

def array_returner() -> List[str]:
    return ["hello", "there"]
