這樣我們能得到工具支援，對於編輯器與 mypy 來說，這段程式碼在型別上是正確的，同時我們也能得到 FastAPI 的資料過濾。

這是怎麼運作的？來看一下。🤓

### 型別註解與工具支援 { #type-annotations-and-tooling }

先看看編輯器、mypy 與其他工具會怎麼看這件事。

`BaseUser` 有基礎欄位。然後 `UserIn` 繼承自 `BaseUser` 並新增 `password` 欄位，因此它會包含兩個模型的所有欄位。

我們把函式回傳型別註解為 `BaseUser`，但實際上回傳的是 `UserIn` 實例。

編輯器、mypy 與其他工具不會抱怨，因為就型別學而言，`UserIn` 是 `BaseUser` 的子類別，這代表當預期任何 `BaseUser` 時，`UserIn` 是一個有效的型別。
