Tất cả được dựa trên khai báo kiểu dữ liệu chuẩn của **Python 3.8** (cảm ơn Pydantic). Bạn không cần học cú pháp mới, chỉ cần biết chuẩn Python hiện đại.

Nếu bạn cần 2 phút để làm mới lại cách sử dụng các kiểu dữ liệu mới của Python (thậm chí nếu bạn không sử dụng FastAPI), xem hướng dẫn ngắn: [Kiểu dữ liệu Python](python-types.md){.internal-link target=_blank}.

Bạn viết chuẩn Python với kiểu dữ liệu như sau:

```Python

Bây giờ, bạn chỉ cần biết rằng `Annotated` tồn tại, và nó là tiêu chuẩn của Python. 😎


Sau đó, bạn sẽ thấy sự **mạnh mẽ** mà nó có thể làm.
