## Мотивация

Давайте начнем с простого примера:

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

Вызов этой программы выводит:

```
John Doe
```

Функция делает следующее:

* Принимает `first_name` и `last_name`.
* Преобразует первую букву содержимого каждой переменной в верхний регистр с `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()`.

    return User(name="John", surname="Doe")
