### Membuat class `Enum`

Import `Enum` dan buat *sub-class* warisan dari `str` dan `Enum`.

Dengan warisan dari `str` dokumen API mengetahui nilai nya harus berjenis `string` supaya bisa digunakan dengan benar.

Kemudian buat atribut *class* dengan nilai tetap *string* yang benar:

{* ../../docs_src/path_params/tutorial005.py hl[1,6:9] *}

   * {@linkplain Thread#getContextClassLoader() context class loader}. In simple environments, the
   * context class loader will find resources from the class path. In environments where different
   * threads can have different class loaders, for example app servers, the context class loader
   * will typically have been set to an appropriate loader for the current thread.
