<summary>À propos de la commande <code>uvicorn main:app --reload</code> ...</summary>

La commande `uvicorn main:app` fait référence à :

* `main` : le fichier `main.py` (le "module" Python).
* `app` : l'objet créé à l'intérieur de `main.py` avec la ligne `app = FastAPI()`.
* `--reload` : fait redémarrer le serveur après des changements de code. À n'utiliser que pour le développement.

```console
$ cd ~/code/prisoner-of-azkaban

$ python main.py

// 匯入 sirius 錯誤，未安裝 😱
Traceback (most recent call last):
    File "main.py", line 1, in <module>

但如果你停用虛擬環境並啟用 `prisoner-of-askaban` 的新虛擬環境，那麼當你執行 `python` 時，它會使用 `prisoner-of-askaban` 中虛擬環境的 Python。

<div class="termy">

```console

하지만 `마법사의 돌(philosophers-stone)`의 가상 환경을 비활성화한 다음, `아즈카반의 죄수(prisoner-of-azkaban)` 프로젝트의 가상 환경을 활성화하면, 이제 `python` 명령어는 `아즈카반의 죄수(prisoner-of-azkaban)` 가상 환경의 Python을 사용하게 됩니다.
