我正在尝试监控Macbook上的击键，以便构建统计分析器。但是我怎样才能将这些字符与“事件”隔离开来，这更像是：
NSEvent：type = KeyDown loc =（850,248）time = 66551.8 flags = 0x100 win = 0x0 winNum = 0 ctxt = 0x0 chars =“l”unmodchars =“l”repeat = 0 keyCode = 37
所以有人知道如何根据下面发布的脚本，使用chars（来自NSEvent）的值来实现一个.txt doc吗？我需要一个带有按键的文本文件，以便在其上运行我的其他脚本并分析频率等...
提前致谢;）

我挖了一下，发现github用户'gurgeh的OSX修改为他的分支中的selfspy - https://github.com/gurgeh/selfspy/blob/new_activity/sniff_cocoa.py。
我把一些自己的想法融入其中，这就是结果。感谢gurgeh如何捕获窗口更改事件 - 这使得关键记录器更加有趣，因为您基本上可以忽略不提供有趣事件的应用程序，或者对于具有统计意义的图表，您可以使用最多的应用程序和你正在做什么..

使用Keycode模块。只需从这里克隆它并运行＆＃34; sudo setup.py install＆＃34; 。你将拥有keycode模块 https://github.com/abarnert/pykeycode
