//// tab | 🐍 3️⃣.6️⃣ & 🔛

```Python hl_lines="11-14"
{!> ../../docs_src/body_fields/tutorial001.py!}
```

////

//// tab | 🐍 3️⃣.1️⃣0️⃣ & 🔛

```Python hl_lines="9-12"
{!> ../../docs_src/body_fields/tutorial001_py310.py!}
```

////

///

## Declare model attributes

You can then use `Field` with model attributes:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

`Field` works the same way as `Query`, `Path` and `Body`, it has all the same parameters, etc.
