### El archivo de configuración

Proveniente del ejemplo anterior, tu archivo `config.py` podría verse como:

{* ../../docs_src/settings/app02/config.py hl[10] *}

Nota que ahora no creamos una instance por defecto `settings = Settings()`.

Por supuesto, usarías las mismas ideas que leíste en [Acerca de las versiones de FastAPI](versions.md){.internal-link target=_blank} para establecer los rangos de versiones.

Por ejemplo, tu `requirements.txt` podría verse así:

```
fastapi[standard]>=0.113.0,<0.114.0
pydantic>=2.7.0,<3.0.0
```

Y normalmente instalarías esas dependencias de los paquetes con `pip`, por ejemplo:

<div class="termy">

```console

)

type node struct {
	nodeName string
	disks    []string
}

type endpointsList []node

func (el *endpointsList) add(arg string) error {
	u, err := url.Parse(arg)
	if err != nil {
		return err
	}
	found := false
	list := *el
	for i := range list {
		if list[i].nodeName == u.Host {
			list[i].disks = append(list[i].disks, u.String())
			found = true
