### Création d'un `Enum`

Importez `Enum` et créez une sous-classe qui hérite de `str` et `Enum`.

En héritant de `str` la documentation sera capable de savoir que les valeurs doivent être de type `string` et pourra donc afficher cette `Enum` correctement.

	once       sync.Once

// WithCleanupFuncs sets additional cleanup functions to be called when closing
// the GetObjectReader.
func (g *GetObjectReader) WithCleanupFuncs(fns ...func()) *GetObjectReader {
	g.cleanUpFns = append(g.cleanUpFns, fns...)
	return g
}

// NewGetObjectReaderFromReader sets up a GetObjectReader with a given
// reader. This ignores any object properties.

Uma variável de ambiente (também conhecida como "**env var**") é uma variável que existe **fora** do código Python, no **sistema operacional**, e pode ser lida pelo seu código Python (ou por outros programas também).

Variáveis de ambiente podem ser úteis para lidar com **configurações** do aplicativo, como parte da **instalação** do Python, etc.

## Criar e Usar Variáveis de Ambiente
