Returns a named - 2-tuple of sets. The first set, named "done", contains the futures that - completed (finished or were cancelled) before the wait completed. The second - set, named "not_done", contains uncompleted futures. - - *timeout* can be used to control the maximum number of seconds to wait before - returning. *timeout* can be an int or float. If *timeout* is not specified or - ``None`` then there is no limit to the wait time. - - *return_when* indicates when this function should return. It must be one of - the following constants: - - +-----------------------------+----------------------------------------+ - | Constant | Description | - +=============================+========================================+ - | :const:`FIRST_COMPLETED` | The function will return when any | - | | future finishes or is cancelled. | - +-----------------------------+----------------------------------------+ - | :const:`FIRST_EXCEPTION` | The function will return when any | - | | future finishes by raising an | - | | exception.

Any futures that completed - before :func:`as_completed()` was called will be yielded first. The returned - iterator raises a :exc:`TimeoutError` if :meth:`__next__()` is called and - the result isn't available after *timeout* seconds from the original call - to :func:`as_completed()`. *timeout* can be an int or float.
