## Аннотация типа или `Depends`

Обратите внимание, что в приведенном выше коде мы два раза пишем `CommonQueryParams`:

=== "Python 3.6+ без Annotated"

    !!! tip "Подсказка"
        Рекомендуется использовать версию с `Annotated` если возможно.

    ```Python
    commons: CommonQueryParams = Depends(CommonQueryParams)
    ```

app = FastAPI()


async def common_parameters(q: str | None = None, skip: int = 0, limit: int = 100):
    return {"q": q, "skip": skip, "limit": limit}


@app.get("/items/")
async def read_items(commons: dict = Depends(common_parameters)):
    return {"message": "Hello Items!", "params": commons}


@app.get("/users/")
async def read_users(commons: dict = Depends(common_parameters)):

    {!> ../../../docs_src/dependencies/tutorial002_py310.py!}
    ```

**FastAPI** 🤙 `CommonQueryParams` 🎓. 👉 ✍ "👐" 👈 🎓 & 👐 🔜 🚶‍♀️ 🔢 `commons` 👆 🔢.

## 🆎 ✍ 🆚 `Depends`

👀 ❔ 👥 ✍ `CommonQueryParams` 🕐 🔛 📟:

```Python
commons: CommonQueryParams = Depends(CommonQueryParams)
```

🏁 `CommonQueryParams`,:

```Python
... = Depends(CommonQueryParams)
