```

### Es ausprobieren

Jetzt sollten Sie in der Lage sein, zu Ihrer Dokumentation auf <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a> zu gehen und die Seite neu zuladen, die Assets werden nun vom neuen CDN geladen.

# Concurrence et les mots-clés async et await

Cette page vise à fournir des détails sur la syntaxe `async def` pour les *fonctions de chemins* et quelques rappels sur le code asynchrone, la concurrence et le parallélisme.

## Vous êtes pressés ?

<abbr title="'too long; didn't read' en anglais, ou 'trop long ; j'ai pas lu'"><strong>TL;DR :</strong></abbr>

Si vous utilisez des bibliothèques tierces qui nécessitent d'être appelées avec `await`, telles que :

Now you know that you have to fix it, convert `age` to a string with `str(age)`:

```Python hl_lines="2"
{!../../../docs_src/python_types/tutorial004.py!}
```

## Declaring types
