# Parámetros de Path y Validaciones Numéricas

De la misma manera que puedes declarar más validaciones y metadatos para los parámetros de query con `Query`, puedes declarar el mismo tipo de validaciones y metadatos para los parámetros de path con `Path`.

## Importar Path

Primero, importa `Path` de `fastapi`, e importa `Annotated`:

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[1,3] *}

# renaming the wheels as uploading to PyPI would fail with "File already exists"
# error. In order to upload to PyPI, we unpack the wheel and change the tag
# inside a metadata file to the one we want (e.g cp38-cp38-win_amd) and then
# re-pack it to generate it as a platform specific wheel with this new wheel
#tag.
python3 -m wheel unpack "${pure_python_whl}"

# Remove the pure python wheel.

## Metadaten deklarieren

Sie können die gleichen Parameter deklarieren wie für `Query`.

Um zum Beispiel einen `title`-Metadaten-Wert für den Pfad-Parameter `item_id` zu deklarieren, schreiben Sie:

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[10] *}

		EventName:         args.EventName,
		UserIdentity:      event.Identity{PrincipalID: args.ReqParams["principalId"]},
		RequestParameters: args.ReqParams,
		ResponseElements:  respElements,
		S3: event.Metadata{
			SchemaVersion:   "1.0",
			ConfigurationID: "Config",
			Bucket: event.Bucket{
				Name:          args.BucketName,
				OwnerIdentity: event.Identity{PrincipalID: args.ReqParams["principalId"]},

## `UploadFile` con Metadatos Adicionales

También puedes usar `File()` con `UploadFile`, por ejemplo, para establecer metadatos adicionales:

{* ../../docs_src/request_files/tutorial001_03_an_py39.py hl[9,15] *}

		key := "obj" + strconv.Itoa(i)
		objects[key] = []byte(randomString)
		metadata := make(map[string]string)
		metadata["etag"] = expectedETaghex
		var objInfo ObjectInfo
		objInfo, err = obj.PutObject(context.Background(), "bucket", key, mustGetPutObjReader(t, bytes.NewBufferString(randomString), int64(len(randomString)), metadata["etag"], ""), ObjectOptions{UserDefined: metadata})
		if err != nil {
