#### Data with the same values as the defaults { #data-with-the-same-values-as-the-defaults }

If the data has the same values as the default ones, like the item with ID `baz`:

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

#### Dados com os mesmos valores que os padrões { #data-with-the-same-values-as-the-defaults }

Se os dados tiverem os mesmos valores que os padrões, como o item com ID `baz`:

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

#### Default değerlerle aynı değerlere sahip data { #data-with-the-same-values-as-the-defaults }

Eğer data, default değerlerle aynı değerlere sahipse, örneğin ID’si `baz` olan item gibi:

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

#### Daten mit den gleichen Werten wie die Defaultwerte { #data-with-the-same-values-as-the-defaults }

Wenn Daten die gleichen Werte haben wie ihre Defaultwerte, wie etwa der Artikel mit der ID `baz`:

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