# Esempi per Systems Manager con SDK per Python (Boto3)
<a name="python_3_ssm_code_examples"></a>

I seguenti esempi di codice mostrano come eseguire azioni e implementare scenari comuni utilizzando AWS SDK per Python (Boto3) with Systems Manager.

*Nozioni di base*: esempi di codice che mostrano come eseguire le operazioni essenziali all’interno di un servizio.

Le *azioni* sono estratti di codice da programmi più grandi e devono essere eseguite nel contesto. Sebbene le azioni mostrino come richiamare le singole funzioni del servizio, è possibile visualizzarle contestualizzate negli scenari correlati.

Ogni esempio include un link al codice sorgente completo, in cui vengono fornite le istruzioni su come configurare ed eseguire il codice nel contesto.
