Now you can create the *path operations* for the custom docs.

You can re-use FastAPI's internal functions to create the HTML pages for the docs, and pass them the needed arguments:

* `openapi_url`: the URL where the HTML page for the docs can get the OpenAPI schema for your API. You can use here the attribute `app.openapi_url`.
* `title`: the title of your API.
* `oauth2_redirect_url`: you can use `app.swagger_ui_oauth2_redirect_url` here to use the default.

Editör değişkenlerin tiplerini bildiğinden, yalnızca otomatik tamamlama değil, hata kontrolleri de sağlar:

Artık `age` değişkenini `str(age)` olarak kullanmanız gerektiğini biliyorsunuz:

```Python hl_lines="2"
{!../../../docs_src/python_types/tutorial004.py!}
```

## Tip bildirme

<img src="https://fastapi.tiangolo.com/img/python-types/image04.png">

Ahora que sabes que tienes que arreglarlo convierte `age` a un string con `str(age)`:

```Python hl_lines="2"
{!../../../docs_src/python_types/tutorial004.py!}
```

## Declarando tipos

Como o editor conhece os tipos de variáveis, você não apenas obtém a conclusão, mas também as verificações de erro:

<img src="/img/python-types/image04.png">

Agora você sabe que precisa corrigí-lo, converta `age` em uma string com `str (age)`:

```Python hl_lines="2"
{!../../../docs_src/python_types/tutorial004.py!}
```

## Tipos de declaração

def on_pre_page(page: Page, *, config: MkDocsConfig, files: Files) -> Page:
    return page


def on_page_markdown(
    markdown: str, *, page: Page, config: MkDocsConfig, files: Files
) -> str:
    if isinstance(page.file, EnFile):
        for excluded_section in non_traslated_sections:
            if page.file.src_path.startswith(excluded_section):

<img src="/img/python-types/image04.png">

Maintenant que vous avez connaissance du problème, convertissez `age` en <abbr title="string">chaîne de caractères</abbr> grâce à `str(age)` :

```Python hl_lines="2"
{!../../../docs_src/python_types/tutorial004.py!}
```

## Déclarer des types

## 使用 CLI 登录

现在，使用 CLI 登录 Deta：

<div class="termy">

```console
$ deta login

Please, log in from the web page. Waiting..
Logged in successfully.
```

</div>

这个命令会打开浏览器并自动验证身份。

## 使用 Deta 部署

接下来，使用 Deta CLI 部署应用：

<div class="termy">

```console
$ deta new

    browser = playwright.chromium.launch(headless=False)
    context = browser.new_context(viewport={"width": 960, "height": 1080})
    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_role("button", name="Item", exact=True).click()
    page.set_viewport_size({"width": 960, "height": 700})
    page.screenshot(
        path="docs/en/docs/img/tutorial/separate-openapi-schemas/image05.png"
    )
