* La variable `items_s` est un `set`, et chacun de ses éléments est de type `bytes`.

#### `Dict`

Pour définir un `dict`, il faut lui passer 2 paramètres, séparés par une virgule (`,`).

Le premier paramètre de type est pour les clés et le second pour les valeurs du dictionnaire (`dict`).

{*../../docs_src/python_types/tutorial008.py hl[1,4] *}

Dans cet exemple :

* La variable `prices` est de type `dict` :

                if ( !Objects.equals(getServerWithDfs(), dest.getServerWithDfs()) || !Objects.equals(getShare(), dest.getShare()) ) {
                    throw new SmbException("Cannot rename between different trees");
                }
            }

            if ( log.isDebugEnabled() ) {
                log.debug("renameTo: " + getUncPath() + " -> " + dest.getUncPath());
            }

## Investigation

By using all the previous alternatives I had the chance to learn from all of them, take ideas, and combine them in the best way I could find for myself and the teams of developers I have worked with.

O benefício de lançar uma exceção em vez de retornar um valor ficará mais evidente na seção sobre Dependências e Segurança.

Neste exemplo, quando o cliente pede, na requisição, por um item cujo ID não existe, a exceção com o status code `404` é lançada:

```Python hl_lines="11"
