Then create class attributes with fixed values, which will be the available valid values:

```Python hl_lines="1  6-9"
{!../../docs_src/path_params/tutorial005.py!}
```

/// info

<a href="https://docs.python.org/3/library/enum.html" class="external-link" target="_blank">Enumerations (or enums) are available in Python</a> since version 3.4.

///

/// tip

Luego crea atributos de clase con valores fijos, que serán los valores disponibles válidos:

```Python hl_lines="1  6-9"
{!../../docs_src/path_params/tutorial005.py!}
```

/// info | Información

Las <a href="https://docs.python.org/3/library/enum.html" class="external-link" target="_blank">Enumerations (o enums) están disponibles en Python</a> desde la versión 3.4.

my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

/// info | "Информация"

`**second_user_data` означает:

Передать ключи и значения словаря `second_user_data`,  в качестве аргументов типа "ключ-значение", это эквивалентно: `User(id=4, name="Mary", joined="2018-11-30")` .

また、その結果のオブジェクトですべてのエディタのサポートを受けることができます。
