## Example upgrade { #example-upgrade }

Now modify the file `main.py` to receive a body from a `PUT` request.

Declare the body using standard Python types, thanks to Pydantic.

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()

## Campos de lista

Puedes definir un atributo como un subtipo. Por ejemplo, una `list` en Python:

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

Esto hará que `tags` sea una lista, aunque no declare el tipo de los elementos de la lista.

## Campos de lista con parámetro de tipo

Pero Python tiene una forma específica de declarar listas con tipos internos, o "parámetros de tipo":

### Importar `List` de typing

    }

    /**
     * Deletes all URL filters for the specified session.
     *
     * @param sessionId The session ID.
     */
    @Override
    public void delete(final String sessionId) {
        deleteBySessionId(sessionId);
        includeFilterCache.invalidate(sessionId);
        excludeFilterCache.invalidate(sessionId);
    }

    /**

  }

  /**
   * Returns the {@linkplain #getSampleElements() sample elements} as ordered by {@link
   * TestContainerGenerator#order(List)}. Tests should use this method only if they declare
   * requirement {@link com.google.common.collect.testing.features.CollectionFeature#KNOWN_ORDER}.
   */
  protected List<E> getOrderedElements() {
    List<E> list = new ArrayList<>();

/**

public class HcHttpClientTest extends PlainTestCase {
    public HcHttpClient httpClient;

    public UrlFilter urlFilter;

    @Override

#### List

Por exemplo, vamos definir uma variável para ser uma `list` de `str`.

//// tab | Python 3.9+

Declare uma variável com a mesma sintaxe com dois pontos (`:`)

Como tipo, coloque `list`.

Como a lista é o tipo que contém algum tipo interno, você coloca o tipo dentro de colchetes:

```Python hl_lines="1"

	globalOperationTimeout       = newDynamicTimeout(10*time.Minute, 5*time.Minute) // default timeout for general ops
	globalDeleteOperationTimeout = newDynamicTimeout(5*time.Minute, 1*time.Minute)  // default time for delete ops

	globalBucketObjectLockSys *BucketObjectLockSys
	globalBucketQuotaSys      *BucketQuotaSys
	globalBucketVersioningSys *BucketVersioningSys

	// Allocated etcd endpoint for config and bucket DNS.
