1、找到python的安裝目錄在python （版本號）libidlelib目錄下

添加Clearwindow.py文件

源代碼如下：

class ClearWindow: menudefs = [ (’options’, [None, (’Clear Shell Window’, ’<<clear-window>>’), ]), ] def __init__(self, editwin): self.editwin = editwin self.text = self.editwin.text self.text.bind('<<clear-window>>', self.clear_window2) self.text.bind('<<undo>>', self.undo_event) # add='+' doesn’t work def undo_event(self, event): text = self.text text.mark_set('iomark2', 'iomark') text.mark_set('insert2', 'insert') self.editwin.undo.undo_event(event) # fix iomark and insert text.mark_set('iomark', 'iomark2') text.mark_set('insert', 'insert2') text.mark_unset('iomark2') text.mark_unset('insert2') def clear_window2(self, event): # Alternative method # work around the ModifiedUndoDelegator text = self.text text.undo_block_start() text.mark_set('iomark2', 'iomark') text.mark_set('iomark', 1.0) text.delete(1.0, 'iomark2 linestart') text.mark_set('iomark', 'iomark2') text.mark_unset('iomark2') text.undo_block_stop() if self.text.compare(’insert’, ’<’, ’iomark’): self.text.mark_set(’insert’, ’end-1c’) self.editwin.set_line_and_column() def clear_window(self, event): # remove undo delegator undo = self.editwin.undo self.editwin.per.removefilter(undo) # clear the window, but preserve current command self.text.delete(1.0, 'iomark linestart') if self.text.compare(’insert’, ’<’, ’iomark’): self.text.mark_set(’insert’, ’end-1c’) self.editwin.set_line_and_column() # restore undo delegator self.editwin.per.insertfilter(undo)

2、繼續在當前目錄下（python （版本號）libidlelib）打開編輯config-extensions.def（IDLE擴展配置文件）

在原文件下添加如下代碼：

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

3、重新啟動IDLE，點擊Options，可看到：

輸入一些代碼

Ctrl+w
