Traceback (most recent call last):

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

<div class="termy">

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

$ python main.py

// 导入 sirius 报错，它没有安装 😱
Traceback (most recent call last):
    File "main.py", line 1, in <module>
        import sirius
```

</div>

但是如果你停用虚拟环境并激活 `prisoner-of-askaban` 的新虚拟环境，那么当你运行 `python` 时，它会使用 `prisoner-of-askaban` 中的虚拟环境中的 Python。

<div class="termy">

```console

<div class="termy">

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

$ python main.py

// sirius를 임포트하는 데 실패했습니다. 설치되어 있지 않아요 😱
Traceback (most recent call last):
    File "main.py", line 1, in <module>
        import sirius
```

</div>

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.

<div class="termy">

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

$ python main.py

// Error importing sirius, it's not installed 😱
Traceback (most recent call last):
    File "main.py", line 1, in <module>
        import sirius
```

</div>

しかし、その仮想環境を無効化し、 `prisoner-of-azkaban` （アズカバンの囚人）のための新しい仮想環境を有効にすれば、 `python` を実行したときに `prisoner-of-azkaban` （アズカバンの囚人）の仮想環境の Python が使用されるようになります。

Ici, nous réutilisons le même modèle Pydantic.

Mais nous aurions pu tout aussi bien pu le valider d'une autre manière.
