### 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
    first_name: str, last_name: str
```

就是这样。

这些就是“类型提示”：

{* ../../docs_src/python_types/tutorial002_py310.py hl[1] *}

这和声明默认值不同，比如：

```Python
    first_name="john", last_name="doe"
```

这是两码事。

我们用的是冒号（`:`），不是等号（`=`）。

而且添加类型提示通常不会改变代码本来的行为。

     * @param localPort the local port to bind to
     * @param hostName the server host name
     * @param exclusive
     *            whether to acquire an unshared connection
     * @return a transport connection to the target
