## 從 docstring 取得描述 { #description-from-docstring }

由於描述常常較長、跨越多行，你可以在函式的 <dfn title="用於文件的多行字串，作為函式內的第一個運算式（不賦值給任何變數）">文件字串（docstring）</dfn> 中宣告「路徑操作」的描述，**FastAPI** 會從那裡讀取。

你可以在 docstring 中書寫 [Markdown](https://en.wikipedia.org/wiki/Markdown)，它會被正確解析並顯示（會考慮 docstring 的縮排）。

Now, let's see how you could use that to return a custom response.

Let's say that you want to return an [XML](https://en.wikipedia.org/wiki/XML) response.

You could put your XML content in a string, put that in a `Response`, and return it:
