Within one such session, interaction with many applications can happen, one after the other. The input/output device is not supposed to change during one session. Warning: Always use the `create_app_session` function to create an instance, so that it gets activated correctly. :param input: Use this as a default input for all applications running in this session, unless an input is passed to the `Application` explicitly. :param output: Use this as a default output.

An :class:`.Application` is active during the :meth:`.Application.run_async` call. We assume that there can only be one :class:`.Application` active at the same time. There is only one terminal window, with only one stdin and stdout. This makes the code significantly easier than passing around the :class:`.Application` everywhere. If no :class:`.Application` is running, then return by default a :class:`.DummyApplication`. For practical reasons, we prefer to not raise an exception. This way, we don't have to check all over the place whether an actual `Application` was returned. (For applications like pymux where we can have more than one `Application`, we'll use a work-around to handle that.)

This should only be called by the `Application` itself. The application will automatically be active while its running. If you want the application to be active in other threads/coroutines, where that's not the case, use `contextvars.copy_context()`, or use `Application.context` to run it in the appropriate context.
