## Aguardar por mensagens e enviar mensagens

Em sua rota WebSocket você pode esperar (`await`) por mensagens e enviar mensagens.

{*../../docs_src/websockets/tutorial001.py hl[48:52]*}

Você pode receber e enviar dados binários, de texto e JSON.

## Tente você mesmo

In recent versions of Python, there's also an **async context manager**. You would use it with `async with`:

```Python

    await do_stuff()
