As *noções básicas* são exemplos de código que mostram como realizar as operações essenciais em um serviço. *Ações* são trechos de código de programas maiores e devem ser executadas em contexto. Embora as ações mostrem como chamar perfis de serviço individuais, você pode ver as ações no contexto em seus cenários relacionados. Cada exemplo inclui um link para o código-fonte completo, em que você pode encontrar instruções sobre como configurar e executar o código. **Topics** + [Conceitos básicos](#basics) + [Ações](#actions) ## Conceitos básicos ### Conheça os conceitos básicos O exemplo de código a seguir mostra como: + Solicitar um certificado do ACM. + Importar um certificado autoassinado. + Listar e descrever certificados. + Remover certificados. **SDK para Python (Boto3)** Tem mais sobre GitHub. Encontre o exemplo completo e saiba como configurar e executar no [AWS Code Examples Repository](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/python/example_code/acm#code-examples).
