# Exemples de code pour Forecast à l'aide de AWS SDKs
<a name="forecast_code_examples"></a>

Les exemples de code suivants vous montrent comment utiliser Amazon Forecast avec un kit de développement AWS logiciel (SDK).

Les *actions* sont des extraits de code de programmes plus larges et doivent être exécutées dans leur contexte. Alors que les actions vous indiquent comment appeler des fonctions de service individuelles, vous pouvez les voir en contexte dans leurs scénarios associés.
