Wie Sie sehen, ist die Funktion mit einem `@asynccontextmanager` versehen.

Dadurch wird die Funktion in einen sogenannten „**asynchronen Kontextmanager**“ umgewandelt.

{* ../../docs_src/events/tutorial003.py hl[1,13] *}

Ein **Kontextmanager** in Python ist etwas, das Sie in einer `with`-Anweisung verwenden können, zum Beispiel kann `open()` als Kontextmanager verwendet werden:

```Python
with open("file.txt") as file:
    file.read()

          val extensions = WebSocketExtensions.parse(response.headers)
          ******@****.***ions = extensions
          if (!extensions.isValid()) {
            synchronized(this@RealWebSocket) {
              messageAndCloseQueue.clear() // Don't transmit any messages.
              close(1010, "unexpected Sec-WebSocket-Extensions in response header")

            });
        }
    }
