Exemplos do S3 Glacier usando para SDK Python (Boto3)
Os exemplos de código a seguir mostram como realizar ações e implementar cenários comuns usando o AWS SDK for Python (Boto3) com o S3 Glacier.
Ações são trechos de código de programas maiores e devem ser executadas em contexto. Embora as ações mostrem como chamar funções de serviço individuais, é possível ver as ações no contexto em seus cenários relacionados.
Os cenários são exemplos de código que mostram como realizar tarefas específicas chamando várias funções dentro de um serviço ou combinadas com outros Serviços da AWS.
Cada exemplo inclui um link para o código-fonte completo, onde você pode encontrar instruções sobre como configurar e executar o código no contexto.
