## Chạy mã

Tất cả các code block có thể được sao chép và sử dụng trực tiếp (chúng thực chất là các tệp tin Python đã được kiểm thử).

Để chạy bất kì ví dụ nào, sao chép code tới tệp tin `main.py`, và bắt đầu `uvicorn` với:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
