Python Type hinting with curses

I'm trying to figure out what to put in my type annotation at the top of this function.

I have the following trivial example:

import curses

def main(stdscr):
    stdscr.clear()

    stdscr.addstr(2, 0, "What is the type of stdscr?")
    stdscr.addstr(5, 0, "It is: {}".format(type(stdscr)))

    stdscr.refresh()
    stdscr.getkey()

curses.wrapper(main)

This returns <type '_curses.curses window'>. This doesn't seem like it will work with Type hinting as it has a space in it. The expected result would be WindowObject listed in the documentation. I can't find a path to WindowObject in the curses module itself. EDIT: The documentation is incorrect here.

How do I write main with accurate type annotation?
