要為單一指令設定多個環境變數，只要用空白分隔它們，並全部放在指令前面即可。

///

如此一來，`admin_email` 設定會被設為 `"******@****.***"`。

`app_name` 會是 `"ChimichangApp"`。

而 `items_per_user` 則會保留其預設值 `50`。

## 在另一個模組中的設定 { #settings-in-another-module }

你也可以把這些設定放在另一個模組檔案中，就像在[更大的應用程式 - 多個檔案](../tutorial/bigger-applications.md)所示。

例如，你可以有一個 `config.py` 檔案如下：

{* ../../docs_src/settings/app01_py310/config.py *}

然後在 `main.py` 檔案中使用它：

   *   <li>The visible constructor or visible static factory method with the most parameters is used
   *       to construct the sample instances. In case of tie, the candidate constructors or
   *       factories are tried one after another until one can be used to construct sample
   *       instances.
   *   <li>For the constructor or static factory method used to construct instances, it's checked

				bucketsMap[bi.Name]++

					resultMap[bi.Name] = bi

		}
		// loop through buckets and see if some with lost quorum

	defer locker.Unlock(lkctx)

	// Load healing tracker in this disk
	tracker, err := loadHealingTracker(ctx, disk)
	if err != nil {
		// A healing tracker may be deleted if another disk in the
		// same erasure set with same healing-id successfully finished
		// healing.
		if errors.Is(err, errFileNotFound) {
			return nil
		}

					return

				goto sendResp

		case <-pingTimer:
			if !m.doPing(respHandler) {

	}
}

// doPing checks last ping time and sends another ping.
func (m *muxClient) doPing(respHandler chan<- Response) (ok bool) {
