## Motivations

Prenons un exemple simple :

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

Exécuter ce programe affiche :

```
John Doe
```

La fonction :

* Prend un `first_name` et un `last_name`.
* Convertit la première lettre de chaque paramètre en majuscules grâce à `title()`.
* Concatène les résultats avec un espace entre les deux.

        val extension = this.extensions.create<ErrorProneSourceSetExtension>("errorprone", project.objects.property<Boolean>())
        // Enable it only for the main source set by default, as incremental Groovy
        // joint-compilation doesn't work with the Error Prone annotation processor
        extension.enabled.convention(this.name == "main")

        project.dependencies.addProvider(
            annotationProcessorConfigurationName,

    response = client.get("/users/me", headers={"Authorization": "Bearer johndoe"})
    assert response.status_code == 200, response.text
    assert response.json() == {
        "username": "johndoe",
        "full_name": "John Doe",
        "email": "******@****.***",
        "hashed_password": "fakehashedsecret",
        "disabled": False,
    }

    response = client.get("/users/me", headers={"Authorization": "Bearer johndoe"})
    assert response.status_code == 200, response.text
    assert response.json() == {
        "username": "johndoe",
        "full_name": "John Doe",
        "email": "******@****.***",

client = TestClient(app)


def test_get():

## Motivation

Fangen wir mit einem einfachen Beispiel an:

```Python
{!../../docs_src/python_types/tutorial001.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()`.

///

## Мотивація

Давайте почнемо з простого прикладу:

```Python
{!../../docs_src/python_types/tutorial001.py!}
```

Виклик цієї програми виводить:

```
John Doe
```

Функція виконує наступне:

* Бере `first_name` та `last_name`.
* Конвертує кожну літеру кожного слова у верхній регістр за допомогою `title()`.

## 动机

让我们从一个简单的例子开始：

```Python
{!../../docs_src/python_types/tutorial001.py!}
```

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。
