# Path Parameters and Numeric Validations { #path-parameters-and-numeric-validations }

In the same way that you can declare more validations and metadata for query parameters with `Query`, you can declare the same type of validations and metadata for path parameters with `Path`.

## Import `Path` { #import-path }

First, import `Path` from `fastapi`, and import `Annotated`:

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

# Parámetros de Path y Validaciones Numéricas { #path-parameters-and-numeric-validations }

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 { #import-path }

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

# Pfad-Parameter und Validierung von Zahlen { #path-parameters-and-numeric-validations }

So wie Sie mit `Query` für Query-Parameter zusätzliche Validierungen und Metadaten deklarieren können, können Sie mit `Path` die gleichen Validierungen und Metadaten für Pfad-Parameter deklarieren.

## `Path` importieren { #import-path }

Importieren Sie zuerst `Path` von `fastapi`, und importieren Sie `Annotated`:

# Parâmetros de path e validações numéricas { #path-parameters-and-numeric-validations }

Da mesma forma que você pode declarar mais validações e metadados para parâmetros de consulta com `Query`, você pode declarar o mesmo tipo de validações e metadados para parâmetros de path com `Path`.

## Importe `Path` { #import-path }

Primeiro, importe `Path` de `fastapi`, e importe `Annotated`:

# Path-параметры и валидация числовых данных { #path-parameters-and-numeric-validations }

Так же, как с помощью `Query` вы можете добавлять валидацию и метаданные для query-параметров, так и с помощью `Path` вы можете добавлять такую же валидацию и метаданные для path-параметров.

## Импорт `Path` { #import-path }

Сначала импортируйте `Path` из `fastapi`, а также импортируйте `Annotated`:

	bytes, _ := v.ToBytes()
	return string(bytes)
}

// Calculates minimum or maximum of v and a and assigns the result to
// v - it works only on numeric arguments, where `v` is already
// assumed to be numeric. Attempts conversion to numeric type for `a`
// (first int, then float) only if the underlying values do not have a
// type.
func (v *Value) minmax(a *Value, isMax, isFirstRow bool) error {

      return routes[nextRouteIndex++]
    }
  }

  companion object {
    /** Obtain a host string containing either an actual host name or a numeric IP address. */
    val InetSocketAddress.socketHost: String get() {
      // The InetSocketAddress was specified with a string (either a numeric IP or a host name). If
      // it is a name, all IPs for that name should be tried. If it is an IP address, only that IP
      // address should be tried.

## About HTTP status codes { #about-http-status-codes }

/// note

If you already know what HTTP status codes are, skip to the next section.

///

In HTTP, you send a numeric status code of 3 digits as part of the response.

These status codes have a name associated to recognize them, but the important part is the number.
