如果在含 `yield` 的相依中使用 `try` 區塊，你會接收到使用該相依時拋出的任何例外。

例如，如果在中途的某段程式碼、其他相依，或某個路徑操作中，讓資料庫交易「rollback」或產生了任何例外，你都會在你的相依中接收到該例外。

因此，你可以在相依內用 `except SomeException` 來攔截特定例外。

同樣地，你可以使用 `finally` 來確保無論是否有例外都會執行結束步驟。

## 含 `yield` 的子相依 { #sub-dependencies-with-yield }

你可以擁有任何大小與形狀的子相依與相依樹，而它們都可以（或不）使用 `yield`。
