/// tip | 提示

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：

// metadata stream format:
//
// The stream is s2 compressed.
// https://github.com/klauspost/compress/tree/master/s2#s2-compression
// This ensures integrity and reduces the size typically by at least 50%.
//
// All stream elements are msgpack encoded.
//
// 1 Integer, metacacheStreamVersion of the writer.
// This can be used for managing breaking changes.
