    Create an item with all the information:

    - **name**: each item must have a name
    - **description**: a long description
    - **price**: required

```Python hl_lines="3  5"
{
    "name": "Bar",
    "description": "The bartenders",
    "price": 62,
    "tax": 20.2
}
```
вони будуть включені у відповідь.

#### Дані з тими самими значеннями, що й типові

Якщо дані мають ті самі значення, що й типові, як у елемента з item_id `baz`:

```Python hl_lines="3  5-6"
{
    "name": "Baz",
    "description": None,
    "price": 50.2,
    "tax": 10.5,

```Python hl_lines="3  5-6"
{
    "name": "Baz",
    "description": None,
    "price": 50.2,
    "tax": 10.5,
    "tags": []
}
```

FastAPI достаточно умен (на самом деле, это Pydantic), чтобы понять, что хотя `description`, `tax` и `tags` совпадают со значениями по умолчанию, они были установлены явно (а не взяты из значений по умолчанию).
