## 文档字符串（`docstring`）

描述内容比较长且占用多行时，可以在函数的 <abbr title="函数中作为第一个表达式，用于文档目的的一个多行字符串（并没有被分配个任何变量）">docstring</abbr> 中声明*路径操作*的描述，**FastAPI** 支持从文档字符串中读取描述内容。

文档字符串支持 <a href="https://en.wikipedia.org/wiki/Markdown" class="external-link" target="_blank">Markdown</a>，能正确解析和显示 Markdown 的内容，但要注意文档字符串的缩进。

```Python hl_lines="19-27"
{!../../docs_src/path_operation_configuration/tutorial004.py!}
```
