idle清屏

步驟:

  • 下載一個叫ClearWindow.py 的擴充套件檔案,程式碼如下(將以下程式碼命名為ClearWindow.py,注意大小寫)

      
    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_window)
       def clear_window2(self, event): # Alternative method
           # work around the ModifiedUndoDelegator
           text = self.text
           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")
           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)
  • 開啟python的安裝目錄(預設在C:\Users\Administrator\AppData\Local\Programs\Python\Python36-32\Lib\idlelib,如果實在是找不到安裝的地方,在開始選單中開啟idle,選擇互動模式,輸入程式碼       import os   print(os.getcwd()),輸出的即為python的安裝目錄),找到lib目錄下的idlelib 目錄,然後把上面的程式碼拷貝到idlelib目錄下。找到config-extensions.def 配置檔案開啟,在檔案末尾加入以下配置即完成idle清屏外掛的安裝,清屏快捷鍵 Ctrl + L

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