Если клиент запросит `http://example.com/items/foo` (`item_id` `"foo"`), то он получит статус-код 200 и ответ в формате JSON:

```JSON
{
  "item": "The Foo Wrestlers"
}
```

Но если клиент запросит `http://example.com/items/bar` (несуществующий `item_id` `"bar"`), то он получит статус-код 404 (ошибка "не найдено") и JSON-ответ в виде:

```JSON
{
  "detail": "Item not found"
}
```

### 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:

- `/` এবং `/items/{item_id}` _paths_ এ HTTP অনুরোধ গ্রহণ করে।

Nyisd meg a böngésződ a következő címen: <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>.

A következő JSON választ fogod látni:

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

Máris létrehoztál egy API-t ami:

* HTTP kéréseket fogad a  `/` és `/items/{item_id}` _útvonalakon_.

///

That means: "the variable `items` is a `list`, and each of the items in this list is a `str`".

/// tip

If you use Python 3.9 or above, you don't have to import `List` from `typing`, you can use the same regular `list` type instead.

///

By doing that, your editor can provide support even while processing items from the list:

                        "title": "Message",

                    }
                }
            },
            "Item": {
                "title": "Item",
                "required": [

* look for the subpackage `routers` (the directory at `app/routers/`)...
* and from it, import the submodule `items` (the file at `app/routers/items.py`) and `users` (the file at `app/routers/users.py`)...

The module `items` will have a variable `router` (`items.router`). This is the same one we created in the file `app/routers/items.py`, it's an `APIRouter` object.

And then we do the same for the module `users`.
