GUI界面记事本交互系统

1、需求：gui界面展示交互记事本

2、实现：Tkinter库

3、代码：

```#！/usr/bin/env python ''' 简陋的gui打印界面'''

import os,sys from Tkinter import * def print_log(): # 定义打印按钮函数 if os.path.exists('myday.txt'): f = open('myday.txt','r') for i in f.readlines(): print i print "input other or exit" while True:

        #print "input other or exit"
        text = raw_input('day,now:>>')
        if text == 'exit':
            break
        else:
           f = open('myday.txt','a+')
           f.write(text+'\n')
else:
    print "input other or exit"
    while True:
        text = raw_input('day,now:>>')
        if text == 'exit':
            break
        else:

           f = open('myday.txt','a+')
           f.write(text+'\n')

win = Tk() # Tk的主窗口 win.title('Tkinter')

btn = Button(win,text='print',command=print_log) #定义一个print 按钮 btn.pack(expand=YES,fill=BOTH)

mainloop() # 窗口会一直显示```

4、重构：
