But whenever you need them and go and learn them, know that you can already use them directly in **FastAPI**.

### Pydantic v1 `regex` instead of `pattern`

Before Pydantic version 2 and before FastAPI 0.100.0, the parameter was called `regex` instead of `pattern`, but it's now deprecated.

      Map<? extends Class<? extends S>, ? extends S> map) {
    if (map instanceof ImmutableClassToInstanceMap) {
      @SuppressWarnings("rawtypes") // JDT-based J2KT Java frontend does not permit the direct cast
      Map rawMap = map;
      @SuppressWarnings("unchecked") // covariant casts safe (unmodifiable)
      ImmutableClassToInstanceMap<B> cast = (ImmutableClassToInstanceMap<B>) rawMap;
      return cast;
    }

You can declare multiple path parameters and query parameters at the same time, **FastAPI** knows which is which.

And you don't have to declare them in any specific order.

They will be detected by name:

//// tab | Python 3.10+

```Python hl_lines="6  8"
{!> ../../docs_src/query_params/tutorial004_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="8  10"

Por padrão, o **FastAPI** irá retornar respostas utilizando `JSONResponse`.

Mas você pode sobrescrever esse comportamento utilizando `Response` diretamente, como visto em [Retornando uma Resposta Diretamente](response-directly.md){.internal-link target=_blank}.
