PySimpleGUI | Whats the difference between window() and window.read()?

Question

I was coding a gui from memory and accidentally used the following line in my event loop:

event, value = window()

The proper way is shown as:

event, value = window.read()

Calling print on each one returns the same thing:

window()=('OK', {0: 'asd'})
window.read()=('OK', {0: 'asd'})

Is there a difference? My gui worked perfectly fine. I tried a couple of different tests to break it or figure out what the difference was and couldn't.

Actually, both of them are the same.

    def __call__(self, *args, **kwargs):
        """
        Call window.read but without having to type it out.
        window() == window.read()
        window(timeout=50) == window.read(timeout=50)

        :return: The famous event, values that read returns.
        :rtype:  Tuple[Any, Dict[Any, Any]]
        """
        return self.read(*args, **kwargs)
