#### Cómo funcionan los imports relativos { #how-relative-imports-work }

/// tip | Consejo

Si sabes perfectamente cómo funcionan los imports, continúa a la siguiente sección.

///

Un solo punto `.`, como en:

```Python
from .dependencies import get_token_header
```

significaría:

	return "Remote already exists for this bucket: " + e.Bucket
}

// BucketRemoteLabelInUse remote already exists for this target label.
type BucketRemoteLabelInUse GenericError

func (e BucketRemoteLabelInUse) Error() string {
	return "Remote with this label already exists for this bucket: " + e.Bucket
}

// BucketRemoteArnTypeInvalid arn type for remote is not valid.

     * @return The query processor.
     */
    public static QueryProcessor getQueryProcessor() {
        return getComponent(QUERY_PROCESSOR);
    }

    /**
     * Gets the label type helper component.
     * @return The label type helper.
     */
    public static LabelTypeHelper getLabelTypeHelper() {
        return getComponent(LABEL_TYPE_HELPER);
    }

    /**

 * k). In benchmarks, this implementation performs at least as well as either implementation, and
 * degrades more gracefully for worst-case input.
 *
 * <p>The implementation does not necessarily use a <i>stable</i> sorting algorithm; when multiple
 * equivalent elements are added to it, it is undefined which will come first in the output.

não gostava tanto de história... e olha eu aqui agora dando aulas de "história tech". 😅

Em resumo, **atualize para o FastAPI 0.99.0 ou superior**, e as coisas ficam muito mais **simples, consistentes e intuitivas**, e você não precisa saber todos esses detalhes históricos. 😎...

- The API server now re-uses data encryption keys while the kms v2 plugin key ID is stable.  Data encryption keys are still randomly generated on server start but an atomic counter is used to prevent nonce collisions. ([#116155](https://github.com/kubernetes/kubernetes/pull/116155), [@enj](https://github.com/enj))

## Múltiples parámetros de path y de query { #multiple-path-and-query-parameters }

Puedes declarar múltiples parámetros de path y de query al mismo tiempo, **FastAPI** sabe cuál es cuál.

Y no tienes que declararlos en un orden específico.

Serán detectados por nombre:

### **Networking**
#### Network Policy
* [stable] [NetworkPolicy](https://kubernetes.io/docs/concepts/services-networking/network-policies/) promoted to GA.
  * Additionally adds short name "netpol" for networkpolicies ([#42241](https://github.com/kubernetes/kubernetes/pull/42241), [@xiangpengzhao](https://github.com/xiangpengzhao))

# Variables de Entorno { #environment-variables }

/// tip | Consejo

Si ya sabes qué son las "variables de entorno" y cómo usarlas, siéntete libre de saltarte esto.

///

Una variable de entorno (también conocida como "**env var**") es una variable que vive **fuera** del código de Python, en el **sistema operativo**, y podría ser leída por tu código de Python (o por otros programas también).
