## 匯入 Pydantic 的 `BaseModel` { #import-pydantics-basemodel }

首先，從 `pydantic` 匯入 `BaseModel`：

{* ../../docs_src/body/tutorial001_py310.py hl[2] *}

## 建立你的資料模型 { #create-your-data-model }

接著，你將資料模型宣告為繼承自 `BaseModel` 的類別。

對所有屬性使用標準的 Python 型別：

{* ../../docs_src/body/tutorial001_py310.py hl[5:9] *}

就和宣告查詢參數時一樣，當模型屬性有預設值時，它就不是必填；否則就是必填。使用 `None` 可使其成為選填。
