### Create an `Enum` class

Import `Enum` and create a sub-class that inherits from `str` and from `Enum`.

By inheriting from `str` the API docs will be able to know that the values must be of type `string` and will be able to render correctly.

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

```Python hl_lines="1  6-9"

            RepositorySystem repositorySystem;
            try {
                repositorySystem = container.lookup(RepositorySystem.class);
            } catch (ComponentLookupException e) {
                throw new IllegalStateException("Unable to lookup " + RepositorySystem.class.getName());
            }

            if (mirrors) {
                repositorySystem.injectMirror(session, repositories);
            }

```

### 关于 `__name__ == "__main__"`

`__name__ == "__main__"` 的主要目的是使用以下代码调用文件时执行一些代码：

<div class="termy">

```console
$ python myapp.py
```

</div>

而当其它文件导入它时并不会被调用，像这样：

```Python
from myapp import app
```

#### 更多细节

假设你的文件命名为 `myapp.py`。

如果你这样运行：

<div class="termy">

```console
$ python myapp.py
```

</div>

    }

    @Override
    protected Class<? extends User> typeOfSelectedEntity() {
        return User.class;
    }

    @Override
    protected Class<User> typeOfHandlingEntity() {
        return User.class;
    }

    @Override
    protected Class<UserCB> typeOfHandlingConditionBean() {
        return UserCB.class;
    }

Откройте браузер по адресу: <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a>.

Вы увидите JSON-ответ следующего вида:

```JSON
