Auf diese Weise wird Ihr Handler, wenn irgendein Teil von Starlettes internem Code, oder eine Starlette-Erweiterung, oder -Plugin eine Starlette-`HTTPException` auslöst, in der Lage sein, diese zu fangen und zu handhaben.

Damit wir in diesem Beispiel beide `HTTPException`s im selben Code haben können, benennen wir Starlettes Exception um zu `StarletteHTTPException`:

    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_text("POST/items/Create Item").click()
    page.get_by_role("tab", name="Schema").first.click()
    page.screenshot(
        path="docs/en/docs/img/tutorial/separate-openapi-schemas/image01.png"
    )

                    "loc": ["body", 0, "age"],
                    "msg": "ensure this value is greater than 0",
                    "type": "value_error.number.not_gt",
                }
            ]
        }
    )


def test_put_incorrect_body_multiple():
    response = client.post("/items/", json=[{"age": "five"}, {"age": "six"}])
    assert response.status_code == 422, response.text

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!}
```
