### Create an `Enum` class { #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:

errors.invalid_query_cannot_process=Impossibile elaborare la query specificata.
errors.crud_invalid_mode = Modalità non valida. (È {1}, non {0})
errors.crud_failed_to_create_instance = Impossibile creare nuovi dati.
errors.crud_failed_to_create_crud_table = Impossibile creare nuovi dati. ({0})
errors.crud_failed_to_update_crud_table=Impossibile aggiornare i dati. ({0})
errors.crud_failed_to_delete_crud_table=Impossibile eliminare i dati. ({0})
