<div class="termy">

```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>
        import sirius
```

</div>

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
$ 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
$ 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>

与其他响应类型相比，接受不同的参数集进行实例化：

* `path` - 要流式传输的文件的文件路径。
* `headers` - 任何自定义响应头，传入字典类型。
* `media_type` - 给出媒体类型的字符串。如果未设置，则文件名或路径将用于推断媒体类型。
* `filename` - 如果给出，它将包含在响应的 `Content-Disposition` 中。

文件响应将包含适当的 `Content-Length`，`Last-Modified` 和 `ETag` 的响应头。

### Чтение героев с `HeroPublic` { #read-heroes-with-heropublic }

Аналогично мы можем **читать** `Hero` — снова используем `response_model=list[HeroPublic]`, чтобы данные валидировались и сериализовались корректно.
