``sleep()`` always suspends the current task, allowing other tasks

to run.

The *loop* argument is deprecated and scheduled for removal

in Python 3.10.

The *loop* parameter.

If the wait is cancelled, the future *aw* is also cancelled.

The *loop* parameter.

.. _asyncio_example_waitfor:

set concurrently and block until the condition specified

by *return_when*.

If any awaitable in *aws* is a coroutine, it is automatically

scheduled as a Task. Passing coroutines objects to

``wait()`` directly is deprecated as it leads to

:ref:`confusing behavior <asyncio_example_wait_coroutine>`.

If any awaitable in *aws* is a coroutine, it is automatically

Returns two sets of Tasks/Futures: ``(done, pending)``.

Usage::

done, pending = await asyncio.wait(aws)

*timeout* (a float or int), if specified, can be used to control

the maximum number of seconds to wait before returning.

if task in done:

# Everything will work as expected now.

Passing coroutine objects to ``wait()`` directly is

deprecated.

If *loop* is ``None``, the :func:`get_event_loop` function

is used to get the current loop.

This method is **deprecated** and will be removed in

Python 3.9. Use the :func:`asyncio.all_tasks` function instead.

.. deprecated-removed:: 3.7 3.9

Do not call this as a task method. Use the :func:`asyncio.all_tasks`

function instead.

If *loop* is ``None``, the :func:`get_event_loop` function

is used to get the current loop.

This method is **deprecated** and will be removed in

Python 3.9. Use the :func:`asyncio.current_task` function
