如何更改此Python脚本以成功设置Ubuntu快捷键？

我正在尝试让一个Python脚本工作，该脚本旨在设置Ubuntu快捷键。它在Ubuntu 16.10中似乎不起作用，我不确定为什么。此外，我发现很难跟踪命令、字符串、Bash等所需的引号及其各自的转义

脚本的使用方式如下所示：

./set_Ubuntu_shortkey.py                                                               \
    --command="bash -c \"xvkbd -text \$(date \"+%Y-%m-%dT%H%MZ\" --utc) 2>/dev/null\"" \
    --name="type_time_UTC"                                                             \
    --keys="<Control><Shift>d"

---

不相关，但

如果有（[command，key，name]）则为None

没有任何意义

any（…）

返回一个布尔值，布尔值永远不会是

None

@Rawing感谢您的发现。我已将其更新为更合理的版本（

，如果[command，keys，name]

中没有）。

#!/usr/bin/env python
