# Requestbody

Wenn Sie Daten von einem <abbr title="Client: Eine Software, die sich mit einem Server verbindet.">Client</abbr> (sagen wir, einem Browser) zu Ihrer API senden, dann senden Sie diese als einen **Requestbody** (Deutsch: Anfragekörper).

Ein **Request**body sind Daten, die vom Client zu Ihrer API gesendet werden. Ein **Response**body (Deutsch: Antwortkörper) sind Daten, die Ihre API zum Client sendet.

```

Теперь попробуйте отправить недействительный элемент, например:

```JSON
{
  "title": "towel",
  "size": "XL"
}
```

Вы получите ответ о том, что данные недействительны, содержащий следующее тело:

```JSON hl_lines="12-15"

  "detail": [

# Introduction aux Types Python

Python supporte des annotations de type (ou *type hints*) optionnelles.

Ces annotations de type constituent une syntaxe spéciale qui permet de déclarer le <abbr title="par exemple : str, int, float, bool">type</abbr> d'une variable.

En déclarant les types de vos variables, cela permet aux différents outils comme les éditeurs de texte d'offrir un meilleur support.
