### Python*列挙型*の利用 { #working-with-python-enumerations }

*パスパラメータ*の値は*列挙型メンバ*となります。

#### *列挙型メンバ*の比較 { #compare-enumeration-members }

これは、作成した列挙型 `ModelName` の*列挙型メンバ*と比較できます:

* 首先，確認你**理解了該 Pull Request 想解決的問題**。可能在 GitHub Discussion 或 issue 中有更長的討論。

* 也很有可能這個 Pull Request 其實不需要，因為問題可以用**不同的方法**解決。那你就可以提出或詢問那個方向。

### 不用太在意風格 { #dont-worry-about-style }

* 不要太擔心像是提交訊息（commit message）的風格，我會用 squash and merge 並手動調整提交內容。

* 也不用太在意程式碼風格規範，已經有自動化工具在檢查。

如果還有其他風格或一致性的需求，我會直接提出請求，或是在上面再補上需要的修改提交。

### 檢查程式碼 { #check-the-code }

* 檢查並閱讀程式碼，看看是否合理，**在本機執行**並確認它是否真的解決了問題。
