记事本代码如下：

#创建一个记事本
    #__author__='ZhangP'
    #-*- encoding:utf8 -*-
    
    from tkinter import *

    root.title('记事本')
    
    
    root.geometry("800x500+100+100")
    
    filename=''
    
    def author():
        
        tkinter.messagebox.askokcancel('作者信息','本软件由tiantian520开发')
    
    
    def about():
        
        tkinter.messagebox.askokcancel('版权信息.Copyright','随意转载啦!')
    
    #定义文件子菜单对应的相关函数
