Vous pouvez définir des gestionnaires d'événements (fonctions) qui doivent être exécutés avant le démarrage de l'application, ou lorsque l'application s'arrête.

Ces fonctions peuvent être déclarées avec `async def` ou un `def` normal.

### Événement `startup` { #startup-event }

Pour ajouter une fonction qui doit être exécutée avant le démarrage de l'application, déclarez-la avec l'événement « startup » :

```Python
    first_name="john", last_name="doe"
```

It's a different thing.

We are using colons (`:`), not equals (`=`).

And adding type hints normally doesn't change what happens from what would happen without them.

But now, imagine you are again in the middle of creating that function, but with type hints.

 * A non-blocking interface to a web socket. Use the [factory][WebSocket.Factory] to create

 * Upon normal operation each web socket progresses through a sequence of states:

### Terminology

**Public properties** are formally a part of the Public API.
Public properties are **stable properties**: they CANNOT be renamed or removed without notice.
While we normally deprecate the feature or behavior itself, changes to the property cannot happen in a minor release.
Public properties must be documented.

**Internal properties** are not part of the Public API.

                retValue = retValue.charAt(0) + ":" + retValue.substring(2);
            }

            retValue = new File(retValue).getPath();

        if (retValue == null) {
            retValue = "/";
        }
