## 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。

Abstract

  We're moving toward integrating mojos as first-class plexus components, while
  at the same time avoiding introducing required plexus dependencies into the

## Motivasyon

Basit bir örnek ile başlayalım:

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

Programın çıktısı:

```
John Doe
```

Fonksiyon sırayla şunları yapar:

* `first_name` ve `last_name` değerlerini alır.
* `title()` ile değişkenlerin ilk karakterlerini büyütür.

## Motivação

Vamos começar com um exemplo simples:

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

A chamada deste programa gera:

```
John Doe
```

A função faz o seguinte:

* Pega um `first_name` e `last_name`.
* Converte a primeira letra de cada uma em maiúsculas com `title ()`.
