### Das Problem reproduzieren

In den meisten Fällen und bei den meisten Fragen ist etwas mit dem von der Person erstellten **eigenen Quellcode** los.

In vielen Fällen wird nur ein Fragment des Codes gepostet, aber das reicht nicht aus, um **das Problem zu reproduzieren**.

<img src="/img/python-types/image06.png">

Lưu ý rằng, điều này có nghĩa rằng "`one_person`" là một **thực thể** của lớp `Person`.

Nó không có nghĩa "`one_person`" là một **lớp** gọi là `Person`.

## Pydantic models

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> là một thư viện Python để validate dữ liệu hiệu năng cao.

    * 这个 `dict` 的所有值为 `float` 类型（可以看作是字典内每个元素的价格）。

### 类作为类型

你也可以将类声明为变量的类型。

假设你有一个名为 `Person` 的类，拥有 name 属性：

```Python hl_lines="1-3"
{!../../../docs_src/python_types/tutorial010.py!}
```

接下来，你可以将一个变量声明为 `Person` 类型：

```Python hl_lines="6"
{!../../../docs_src/python_types/tutorial010.py!}
```

然后，你将再次获得所有的编辑器支持：

    They are more relevant for older versions, before OpenAPI 3.1.0 was available.

    You can consider this a brief OpenAPI and JSON Schema **history lesson**. 🤓

!!! warning
    These are very technical details about the standards **JSON Schema** and **OpenAPI**.

* `Set`
* `Dict`
* `Optional`
* ...など

**ジェネリック型** または **ジェネリクス** と呼びます。

### 型としてのクラス

変数の型としてクラスを宣言することもできます。

例えば、`Person`クラスという名前のクラスがあるとしましょう:

```Python hl_lines="1 2 3"
{!../../../docs_src/python_types/tutorial010.py!}
```

変数の型を`Person`として宣言することができます:

```Python hl_lines="6"
{!../../../docs_src/python_types/tutorial010.py!}
```

そして、再び、すべてのエディタのサポートを得ることができます:

Aso, when returning several objects, like in `get_users`, we directly call `list`, like in:

```Python
list(models.User.select())
```

                It can contain several fields.

                * `name`: (`str`) The name of the contact person/organization.
                * `url`: (`str`) A URL pointing to the contact information. MUST be in
                    the format of a URL.
                * `email`: (`str`) The email address of the contact person/organization.
                    MUST be in the format of an email address.
