Now try sending an invalid item like:

```JSON
{
  "title": "towel",
  "size": "XL"
}
```

You will receive a response telling you that the data is invalid containing the received body:

```JSON hl_lines="12-15"
{
  "detail": [
    {
      "loc": [

运行这段程序将输出：

```
John Doe
```

这个函数做了下面这些事情：

* 接收 `first_name` 和 `last_name` 参数。
* 通过 `title()` 将每个参数的第一个字母转换为大写形式。
* 中间用一个空格来<abbr title="将它们按顺序放置组合成一个整体。">拼接</abbr>它们。

### 修改示例

这是一个非常简单的程序。

现在假设你将从头开始编写这段程序。

在某一时刻，你开始定义函数，并且准备好了参数...。
