python LDLE如何实现清屏

相信很多小伙伴在使用pythonIDLE时都会遇到满屏代码而不能清除的烦恼

下面我就给大家介绍一种方法，使得在options下增加一个Clear Shell  Windows | Ctrl +l

首先大家复制这段代码

"""Clear Window Extension
Version: 0.2Author: Roger D. Serwyroger.serwy@gmail.comDate: 2009-06-14It provides "Clear Shell Window" under "Options"
with ability to undo.Add these lines to config-extensions.def[ClearWindow]
enable=1
enable_editor=0
enable_shell=1
[ClearWindow_cfgBindings]
clear-window="""class ClearWindow:menudefs = [('options', [None,('Clear Shell Window', '<>'),]),]def __init__(self, editwin):self.editwin = editwinself.text = self.editwin.textself.text.bind("<>", self.clear_window2)self.text.bind("<>", self.undo_event)  # add="+" doesn't workdef undo_event(self, event):text = self.texttext.mark_set("iomark2", "iomark")text.mark_set("insert2", "insert")self.editwin.undo.undo_event(event)# fix iomark and inserttext.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 ModifiedUndoDelegatortext = self.texttext.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 delegatorundo = self.editwin.undoself.editwin.per.removefilter(undo)# clear the window, but preserve current commandself.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 delegatorself.editwin.per.insertfilter(undo)

然后将它命名为clearwindow.py保存后 

放在python x\lib\idlelib目录下(你的版本号)。

然后在这个目录下找到

config-extensions.def(为了防止出错，先将它备份一份)
config-extensions.def是idle的配置文件然后在这打开的文件后面加上下面的代码[ClearWindow]enable=1enable_editor=0enable_shell=1[ClearWindow_cfgBindings]clear-window=然后保存退出！
再打开python的IDLE就可以在python的options下看见

Clear Shell  Windows | Ctrl +l

然后就可以愉快地用ctre+l进行清屏了。
