pythonshell快捷键_Python3.7.0 Shell添加清屏快捷键的实现示例

1、找到python的安装目录在python (版本号)\lib\idlelib目录下

添加Clearwindow.py文件

源代码如下：

class ClearWindow:

menudefs = [

('options', [None,

('Clear Shell Window', '<>'),

]), ]

def __init__(self, editwin):

self.editwin = editwin

self.text = self.editwin.text

self.text.bind("<>", self.clear_window2)

self.text.bind("<>", 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', '

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', '

self.text.mark_set('insert', 'end-1c')

self.editwin.set_line_and_column()

# restore undo delegator

self.editwin.per.insertfilter(undo)

2、继续在当前目录下(python (版本号)\lib\idlelib)打开编辑config-extensions.def(IDLE扩展配置文件)

在原文件下添加如下代码：

[ClearWindow]

enable=1

enable_editor=0

enable_shell=1

[ClearWindow_cfgBindings]

clear-window=

3、重新启动IDLE，点击Options，可看到：

输入一些代码

Ctrl+w
