max_wait  (duration)  maximum wait time between operations, defaults to '15s'
cycle     (duration)  time duration between scanner cycles
```

Example: the following setting will decrease the scanner speed by a factor of 3, reducing the system resource use, but increasing the latency of updates being reflected.

```sh
~ mc admin config set alias/ scanner delay=30.0
```

// 在此之後這個環境變數將不再存在
$ python main.py

Hello World from Python

## 型別和驗證

這些環境變數只能處理**文字字串**，因為它們是位於 Python 範疇之外的，必須與其他程式和作業系統的其餘部分相容（甚至與不同的作業系統相容，如 Linux、Windows、macOS）。

這意味著從環境變數中讀取的**任何值**在 Python 中都將是一個 `str`，任何型別轉換或驗證都必須在程式碼中完成。
