``websockets`` is a library for building WebSocket servers_ and clients_ in
Python with a focus on correctness and simplicity.

.. _servers: https://github.com/aaugustin/websockets/blob/master/example/server.py
.. _clients: https://github.com/aaugustin/websockets/blob/master/example/client.py

Built on top of :mod:`asyncio`, Python's standard asynchronous I/O framework,
it provides an elegant coroutine-based API.

Here's how a client sends and receives messages:

.. literalinclude:: ../example/hello.py

And here's an echo server:

.. literalinclude:: ../example/echo.py
