Here's how to help others with questions (in discussions or issues):

### Understand the question

* Check if you can understand what is the **purpose** and use case of the person asking.

* Then check if the question (the vast majority are questions) is **clear**.

### 🎓 🆎

👆 💪 📣 🎓 🆎 🔢.

➡️ 💬 👆 ✔️ 🎓 `Person`, ⏮️ 📛:

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

⤴️ 👆 💪 📣 🔢 🆎 `Person`:

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

& ⤴️, 🔄, 👆 🤚 🌐 👨‍🎨 🐕‍🦺:

* `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.
