python清屏插件

今天在使用PythonGUI时，被清屏所困扰，查阅网上资源发现一个比较简单的方式。
在python34/Lib/idellib中加入ClearWindow.py。可以到http://bugs.python.org/file14303/ClearWindow.py下载，或者复制以下代码另存为 ClearWindows.py

##    Clear Window Extension
##

##        with ability to undo.

然后修改config-extensions.def，在末尾添加

[ClearWindow]
enable=1
enable_editor=0
enable_shell=1
[ClearWindow_cfgBindings]
clear-window=<Control-Key-l>

这样一来就可以通过快捷键Ctrl+L来进行清屏了。
网上有一款集成了很多插件的GUI叫 IdleX，将其解压之后放在 Python34/Lib/idlex-1.13，通过python idlex.py可以直接运行，有兴趣的同学可以试试。官网 http://idlex.sourceforge.net
或者大家有更好的方法可以留言一起交流学习。
