        Session session = injector.getInstance(Session.class);
        SessionScope scope = new SessionScope();

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

Da mesma forma, você pode utilizar `finally` para garantir que os passos de saída são executados, com ou sem exceções.

```python hl_lines="3  5"
{!../../docs_src/dependencies/tutorial007.py!}
```

## Subdependências com `yield`

Você pode criar e utilizar variáveis de ambiente no terminal, sem precisar utilizar Python:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// Você pode criar uma env var MY_NAME usando
$ export MY_NAME="Wade Wilson"

                }
                this.completed = true;
            }
            else if ( this.mechContext.isMICAvailable() && ( !this.disableMic || this.requireMic ) ) {
                // we need to send our final data
                mechMIC = calculateMechListMIC();
            }
            else if ( targ.getResult() == NegTokenTarg.REJECTED ) {
                throw new SmbException("SPNEGO mechanism was rejected");

The benefit of raising an exception over `return`ing a value will be more evident in the section about Dependencies and Security.
