* The Certificates API has graduated from alpha to beta. This is a backwards-incompatible change since the alpha support is dropped, and therefore kubeadm v1.5 and v1.6 don't work together (for example kubeadm v1.5 can't join a kubeadm v1.6 cluster).

## Motivation { #motivation }

Fangen wir mit einem einfachen Beispiel an:

{* ../../docs_src/python_types/tutorial001_py39.py *}

Dieses Programm gibt aus:

```
John Doe
```

Die Funktion macht Folgendes:

* Nimmt einen `first_name` und `last_name`.
* Schreibt den ersten Buchstaben eines jeden Wortes groß, mithilfe von `title()`.

    assert response.status_code == 200, response.text
    assert response.json() == {

        "full_name": "John Doe",
        "email": "******@****.***",
        "disabled": False,
    }

            "errorprone",
            project.objects.property<Boolean>()
        ).apply {

            // joint-compilation doesn't work with the Error Prone annotation processor
            enabled.convention(isMainSourceSet)
        }

## 動機

簡単な例から始めてみましょう:

{* ../../docs_src/python_types/tutorial001.py *}


このプログラムを実行すると以下が出力されます:

```
John Doe
```

この関数は以下のようなことを行います:

* `first_name`と`last_name`を取得します。
* `title()`を用いて、それぞれの最初の文字を大文字に変換します。
* 真ん中にスペースを入れて<abbr title="次から次へと中身を入れて一つにまとめる">連結</abbr>します。
