## Importar `Field`

Primero, tienes que importarlo:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}

/// warning | Advertencia

Fíjate que `Field` se importa directamente desde `pydantic`, no desde `fastapi` como el resto (`Query`, `Path`, `Body`, etc).

And then the new OpenAPI 3.1.0 was based on the latest version (JSON Schema 2020-12) that included this new field `examples`.

And now this new `examples` field takes precedence over the old single (and custom) `example` field, that is now deprecated.
