### 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。

# resolve to either
# 1. tensorflow-a.b.c-py3-none-any.whl  or, for nightly builds,
# 2. tf_nightly-a.b.c.devYYYYMMDD-py3-none-any.whl
pure_python_whl=$(ls "$TFCI_OUTPUT_DIR"/*py3-none-any*)
pure_python_whl=$(basename "${pure_python_whl}")

# Extract the package name from the wheel name. That is, extract every character
# before the pattern "-py3-" in the wheel name.
pkg_name=$(echo "${pure_python_whl}" | awk -F'-py3-' '{print $1}')

이전 버전에서 한 줄만 수정해봅시다.

함수의 매개변수인 정확히 이 부분을:

```Python
    first_name, last_name
```

에서:

```Python
    first_name: str, last_name: str
```

로 바꾸겠습니다.

이게 다입니다.

이것들이 "타입 힌트"입니다:

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

이것은 다음처럼 기본값을 선언하는 것과는 다릅니다:

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

다른 것입니다.

등호(`=`)가 아니라 콜론(`:`)을 사용합니다.

publishing.publications.withType<MavenPublication>().configureEach {
    if (name == "pluginMaven") {
        groupId = project.group.toString()
        artifactId = gradleModule.identity.baseName.get()
    }
    pom {
        licenses {
            license {
                name = "The Apache License, Version 2.0"
                url = "http://www.apache.org/licenses/LICENSE-2.0.txt"
            }

先ほどのコードから一行変更してみましょう。

関数のパラメータである次の断片を、以下から:

```Python
    first_name, last_name
```

以下へ変更します:

```Python
    first_name: str, last_name: str
```

これだけです。

それが「型ヒント」です:

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

これは、以下のようにデフォルト値を宣言するのと同じではありません:

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

それとは別物です。

イコール（`=`）ではなく、コロン（`:`）を使用します。
