python目录下的 lib\idlelib 的文件夹下新建文件名为 ClearWindow.py 保存

""" Clear Window Extension Version: 0.2 Author: Roger D. Serwy roger.serwy@gmail.com Date: 2009-06-14 It provides "Clear Shell Window" under "Options" with ability to undo.

python目录下的 lib\idlelib文件夹下，用记事本打开文件config-extensions.def，在文件最后添加一下代码：
[ClearWindow] enable=1 enable_editor=0 enable_shell=1 [ClearWindow_cfgBindings] clear-window=<Control-Key-l>

按步骤来就可以，如果关闭软件没反应可以重启电脑试试。
