Python:一个输入考试测试题的小程序

本意：利用Python和Tkinter作一个考试测试系统，只做了一个输入题目的。请各们高手给出建议。
先看一看运行结果：

功能：增加—保存，在“试题预览”看得到结果，“保存”在“增加”和“编辑”按键后实现，同时更新“试题预览”，”删除" 删除当前的试题，”退出”没有保存文件，直接退出窗口。
代码如下：
1.定义一个stest类：
class Stest():
def init(self,sTitle,answerA,answerB,answerC,answerD,result):
“”“定义单项选择题”""
self.sTitle=sTitle#题目内容
self.tMark=‘■’#题目结束标志
self.answerA=answerA#答案A
self.answerB=answerB#答案A
self.answerC=answerC#答案A
self.answerD=answerD#答案A
self.result=result#正确答案
2.主程序代码：
mport tkinter as tk
from tkinter import scrolledtext
from tkinter.messagebox import *
from tkinter.scrolledtext import *
from Stest import Stest

#定义按钮事件

#保存按钮事件
def bntSf():
#如果有内容为空，则不保存

answerD=TanswerD.get(0.0,‘end’)
i=Snumber.get()
if ((sTitle.strip()’’)or(answerA.strip()’’)or(answerB.strip()’’)or(answerC.strip()’’)or(answerD.strip()==’’) or (Vanswer.get()==0)):
