For example, `dependency_c` can have a dependency on `dependency_b`, and `dependency_b` on `dependency_a`:

```Python hl_lines="6  14  22"

O **FastAPI** garantirá que o "código de saída" em cada dependência com `yield` é executado na ordem correta.

Por exemplo, `dependency_c` pode depender de `dependency_b`, e `dependency_b` depender de `dependency_a`:
