* オプショナルのクエリパラメータ`limit`は`int`で、デフォルトは`100`です。

そして、これらの値を含む`dict`を返します。

### `Depends`のインポート

```Python hl_lines="3"
{!../../../docs_src/dependencies/tutorial001.py!}
```

### "dependant"での依存関係の宣言

*path operation関数*のパラメータに`Body`や`Query`などを使用するのと同じように、新しいパラメータに`Depends`を使用することができます:

```Python hl_lines="13  18"
{!../../../docs_src/dependencies/tutorial001.py!}
```

    return {"item_id": item_id, "q": q}
```

Ha a kódod `async` / `await`-et, használ `async def`:

```Python hl_lines="9  14"
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
async def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

    return {"item_id": item_id, "q": q}
```

<summary>অথবা ব্যবহার করুন <code>async def</code>...</summary>

যদি আপনার কোড `async` / `await`, ব্যবহার করে তাহলে `async def` ব্যবহার করুন:

```Python hl_lines="9  14"
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
async def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
