## Use `Annotated` in the type for the `q` parameter

Remember I told you before that `Annotated` can be used to add metadata to your parameters in the [Python Types Intro](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Now it's the time to use it with FastAPI. 🚀

We had this type annotation:

//// tab | Python 3.10+

```Python
q: str | None = None
```

FastAPI là một web framework hiện đại, hiệu năng cao để xây dựng web APIs với Python dựa trên tiêu chuẩn Python type hints.

Những tính năng như:

* **Nhanh**: Hiệu năng rất cao khi so sánh với **NodeJS** và **Go** (cảm ơn Starlette và Pydantic). [Một trong những Python framework nhanh nhất](#hieu-nang).

     * looking for a way to improve perfomance this is precisly what you
     * would want to do as the jcifs.netbios.SocketXxxputStream classes
     * arraycopy all data read or written into a new buffer shifted over 4!)

Ancak bir noktada, geçmişteki diğer araçlardan en iyi fikirleri alarak bütün bu çözümleri kapsayan, ayrıca bütün bunları Python'ın daha önce mevcut olmayan özelliklerini (Python 3.6+ ile gelen <abbr title="Tip belirteçleri: Type Hints">tip belirteçleri</abbr>) kullanarak yapan bir şey üretmekten başka seçenek kalmamıştı.
