## Importar `Form` { #import-form }

Importar `Form` desde `fastapi`:

{* ../../docs_src/request_forms/tutorial001_an_py310.py hl[3] *}

## Definir parámetros de `Form` { #define-form-parameters }

Crea parámetros de formulario de la misma manera que lo harías para `Body` o `Query`:

{* ../../docs_src/request_forms/tutorial001_an_py310.py hl[9] *}

        verify(mockNdrBuffer, times(1)).enc_ndr_small(100);
        verifyNoMoreInteractions(mockNdrBuffer);
    }

    @Test
    void testDecode() throws NdrException {
        // Define the value that dec_ndr_small should return
        int decodedValue = 200;
        when(mockNdrBuffer.dec_ndr_small()).thenReturn(decodedValue);

        // Create an NdrSmall object (initial value doesn't matter for decode)

---

If you just don't know, use normal `def`.

---

**Note**: You can mix `def` and `async def` in your *path operation functions* as much as you need and define each one using the best option for you. FastAPI will do the right thing with them.

Anyway, in any of the cases above, FastAPI will still work asynchronously and be extremely fast.

If you use any other tool to manage your installations, like `uv`, Poetry, Pipenv, or others, they all have a way that you can use to define specific versions for your packages.

## Available versions { #available-versions }

You can see the available versions (e.g. to check what is the current latest) in the [Release Notes](../release-notes.md).

/// warning

Notice that these parameters are passed directly to the *path operation decorator*, not to your *path operation function*.

///

## Response Status Code { #response-status-code }

You can define the (HTTP) `status_code` to be used in the response of your *path operation*.

You can pass directly the `int` code, like `404`.

# Parâmetros de Cabeçalho { #header-parameters }

Você pode definir parâmetros de Cabeçalho da mesma maneira que define paramêtros com `Query`, `Path` e `Cookie`.

## Importe `Header` { #import-header }

Primeiro importe `Header`:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[3] *}

## Declare parâmetros de `Header` { #declare-header-parameters }
