Embora as ações mostrem como chamar perfis de serviço individuais, você pode ver as ações no contexto em seus cenários relacionados. *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, em que você pode encontrar instruções sobre como configurar e executar o código. **Topics** + [Ações](#actions) + [Cenários](#scenarios) ## Ações ### `CreateVocabulary` O código de exemplo a seguir mostra como usar `CreateVocabulary`. **SDK para Python (Boto3)** Tem mais sobre GitHub.
