### এটা চেক করুন

আপনার ব্রাউজার খুলুন <a href="http://127.0.0.1:8000/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1:8000/items/5?q=somequery</a> এ।

আপনি JSON রেসপন্স দেখতে পাবেন:

```JSON
{"item_id": 5, "q": "somequery"}
```

আপনি ইতিমধ্যে একটি API তৈরি করেছেন যা:

Тогда выполнится условие и эта часть кода:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

будет запущена.

---

Но этого не произойдет, если вы импортируете этот модуль (файл).

Таким образом, если у вас есть файл `importer.py` с таким импортом:

```Python
from myapp import app

</div>

alors la variable interne `__name__` de votre fichier, créée automatiquement par Python, aura pour valeur la chaîne de caractères `"__main__"`.

Ainsi, la section :

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

va s'exécuter.

---

Cela ne se produira pas si vous importez ce module (fichier).

Par exemple, si vous avez un autre fichier `importer.py` qui contient :

```Python
from myapp import app

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

🔜 🏃.

### Testen

Sobald Sie auf <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a> gehen, werden Sie sehen, dass Ihr benutzerdefiniertes Logo verwendet wird (in diesem Beispiel das Logo von **FastAPI**):

    description: str | None = None
    price: float
    tax: float | None = None


@app.put("/items/{item_id}")
async def update_item(
    *,
    item_id: int = Path(title="The ID of the item to get", ge=0, le=1000),
    q: str | None = None,
    item: Item | None = None,
):
    results = {"item_id": item_id}
    if q:
        results.update({"q": q})
    if item:
        results.update({"item": item})

    description: str | None = None
    price: float
    tax: float | None = None


@app.put("/items/{item_id}")
async def update_item(
    item_id: Annotated[int, Path(title="The ID of the item to get", ge=0, le=1000)],
    q: str | None = None,
    item: Item | None = None,
):
    results = {"item_id": item_id}
    if q:
        results.update({"q": q})
    if item:
        results.update({"item": item})

def run(playwright: Playwright) -> None:
    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("GET/items/Read Items").click()
    page.get_by_role("button", name="Try it out").click()
    page.get_by_role("button", name="Execute").click()
    page.screenshot(

```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)

## Check it

Go to the interactive docs at: <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

You will see something like this:

<img src="/img/tutorial/security/image01.png">

```Python hl_lines="9"
{!../../../docs_src/query_params_str_validations/tutorial011.py!}
```

Então, com uma URL assim:

```
http://localhost:8000/items/?q=foo&q=bar
```

você receberá os múltiplos *parâmetros de consulta* `q` com os valores (`foo` e `bar`) em uma lista (`list`) Python dentro da *função de operação de rota*, no *parâmetro da função* `q`.
