但现在想象你要从零开始写它。

在某个时刻你开始定义函数，并且准备好了参数……

接下来你需要调用“那个把首字母变大写的方法”。

是 `upper`？是 `uppercase`？`first_uppercase`？还是 `capitalize`？

然后，你试试程序员的老朋友——编辑器的自动补全。

你输入函数的第一个参数 `first_name`，再输入一个点（`.`），然后按下 `Ctrl+Space` 触发补全。

但很遗憾，没有什么有用的提示：

### 添加类型 { #add-types }

我们来改前一个版本的一行代码。

把函数参数从：

```Python
    first_name, last_name
```

改成：

```Python
