You can set them as follows:

{* ../../docs_src/metadata/tutorial001.py hl[3:16, 19:32] *}

You can write Markdown in the `description` field and it will be rendered in the output.

With this configuration, the automatic API docs would look like:

<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>
<font color="#3465A4">INFO    </font> Resolved absolute path <font color="#75507B">/home/user/code/awesomeapp/</font><font color="#AD7FA8">main.py</font>
<font color="#3465A4">INFO    </font> Searching for package file structure from directories with <font color="#3465A4">__init__.py</font> files

{* ../../docs_src/dependencies/tutorial007.py hl[2:4] *}

The yielded value is what is injected into *path operations* and other dependencies:

{* ../../docs_src/dependencies/tutorial007.py hl[4] *}

The code following the `yield` statement is executed after creating the response but before sending it:

{* ../../docs_src/dependencies/tutorial007.py hl[5:6] *}

/// tip

You can use `async` or regular functions.

{* ../../docs_src/query_params/tutorial001.py hl[9] *}

La partie appelée requête (ou **query**) dans une URL est l'ensemble des paires clés-valeurs placées après le `?` , séparées par des `&`.

Par exemple, dans l'URL :

```

# 最初のステップ

最もシンプルなFastAPIファイルは以下のようになります:

{* ../../docs_src/first_steps/tutorial001.py *}

これを`main.py`にコピーします。

ライブサーバーを実行します:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
<span style="color: green;">INFO</span>:     Started reloader process [28720]

## How it looks { #how-it-looks }

Let's first just use the code and see how it works, and then we'll come back to understand what's happening.

## Create `main.py` { #create-main-py }

Copy the example in a file `main.py`:

{* ../../docs_src/security/tutorial001_an_py39.py *}

## Run it { #run-it }

/// info

{* ../../docs_src/sub_applications/tutorial001.py hl[3,6:8] *}

```console
// Aqui ainda não definimos a variável de ambiente
$ python main.py

// Como não definimos a variável de ambiente, obtemos o valor padrão

Hello World from Python

// Mas se criarmos uma variável de ambiente primeiro
$ export MY_NAME="Wade Wilson"

// E então chamar o programa novamente
$ python main.py

// Agora ele pode ler a variável de ambiente

Hello Wade Wilson from Python
```

Primero, necesitas importar `BaseModel` de `pydantic`:

{* ../../docs_src/body/tutorial001_py310.py hl[2] *}

## Crea tu modelo de datos

Luego, declaras tu modelo de datos como una clase que hereda de `BaseModel`.

Usa tipos estándar de Python para todos los atributos:
