Por exemplo, se algum código em um certo momento no meio, em outra dependência ou em uma *operação de rota*, fizer um "rollback" de uma transação de banco de dados ou causar qualquer outra exceção, você irá capturar a exceção em sua dependência.

Então, você pode procurar por essa exceção específica dentro da dependência com `except AlgumaExcecao`.

their friends had taught them:  such as, that a red-hot poker
will burn you if you hold it too long; and that if you cut your
finger VERY deeply with a knife, it usually bleeds; and she had
never forgotten that, if you drink much from a bottle marked
`poison,' it is almost certain to disagree with you, sooner or
later.
