在2010年的Pycon大会上有一个presentation on cross-platform Python development。

还有一个关于它的html页面，其中包含一些跨平台通知的建议。但是，我在网上找不到它了，但我保存了一个本地副本，这是关于通知的部分：There are occasions in which your application wants to notify the user

about something: software updates are available, a new instant message

have been received, the 300 page print job has finally finished, etc.To keep notifications easy to port cross-platform, don't make

them interactive. For example Ubuntu does not support notifications

that require user interaction.

These are the most important libraries:

o Linux: pynotify.

o Mac OS X: Growl, which is not standard, is usually

installed.

o Windows: a good wxPython solution is ToasterBox of Andrea

Gavana, which mimics the look of Firefox or Thunderbird notifications.

For Phatch we developed a library that unifies these three

systems in one API: phatch/lib/notify.py.

链接的python文件非常有趣，我认为您应该能够像现在这样使用链接的python文件。代码也非常清楚，所以您将很快看到它的作用。

最基本的方法是检测哪些通知系统可用，几乎与平台无关，并尝试按特定顺序使用它们，但如果需要，可以返回到更简单的系统。这样，如果用户安装了例如Growl的软件，不管平台是什么，它都会使用它。

您可以对其进行调整，以便为上述三种通知系统之外的其他通知系统提供支持。
