# Usando Dataclasses

FastAPI está construido sobre **Pydantic**, y te he estado mostrando cómo usar modelos de Pydantic para declarar requests y responses.

Pero FastAPI también soporta el uso de <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> de la misma manera:

{* ../../docs_src/dataclasses/tutorial001.py hl[1,7:12,19:20] *}

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import json
import logging
import urllib
from uuid import uuid4

import boto3
import requests
from botocore.client import Config
from flask import Flask, request

boto3.set_stream_logger('boto3.resources', logging.DEBUG)

authorize_url = "http://localhost:8080/auth/realms/minio/protocol/openid-connect/auth"
token_url = "http://localhost:8080/auth/realms/minio/protocol/openid-connect/token"

Podrías querer probar sus cursos:

* <a href="https://training.talkpython.fm/fastapi-courses" class="external-link" target="_blank">Talk Python Training</a>

FastAPI todavía podrá sobrescribirla.

///

Entonces puedes restablecer las dependencias sobreescritas configurando `app.dependency_overrides` para que sea un `dict` vacío:

```Python
app.dependency_overrides = {}
```

Мы используем <a href="https://docs.python.org/3/library/time.html#time.perf_counter" class="external-link" target="_blank">`time.perf_counter()`</a> вместо `time.time()` для обеспечения большей точности наших примеров. 🤓

### 타입 매개변수로 `List` 선언

`list`, `dict`, `tuple`과 같은 타입 매개변수(내부 타입)를 갖는 타입을 선언하려면:

* `typing` 모듈에서 임포트
* 대괄호를 사용하여 "타입 매개변수"로 내부 타입 전달: `[` 및 `]`

```Python
from typing import List

my_list: List[str]
```

이 모든 것은 타입 선언을 위한 표준 파이썬 문법입니다.

내부 타입을 갖는 모델 어트리뷰트에 대해 동일한 표준 문법을 사용하세요.

마찬가지로 예제에서 `tags`를 구체적으로 "문자열의 리스트"로 만들 수 있습니다:
