要为单个命令设置多个环境变量，只需用空格分隔它们，并把它们都放在命令前面。

///

然后，`admin_email` 设置将为 `"******@****.***"`。

`app_name` 将为 `"ChimichangApp"`。

而 `items_per_user` 会保持默认值 `50`。

## 在另一个模块中放置设置 { #settings-in-another-module }

你可以把这些设置放在另一个模块文件中，就像你在[更大的应用 - 多个文件](../tutorial/bigger-applications.md)中看到的那样。

例如，可以有一个 `config.py` 文件：

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

然后在 `main.py` 文件中使用它：

   * being a real directory to being a symlink to another directory. It then calls
   * deleteDirectoryContents thousands of times on a directory whose subtree contains the file
   * that's switching between directory and symlink to try to ensure that under no circumstance does
   * deleteDirectoryContents follow the symlink to the other directory and delete that directory's
   * contents.
   *
