本文的单项选择题与管理系统通过面向对象实现,调用tkinter完成了基本GUI界面,文件存储方面采用txt格式化存储、读取数据,主要功能围绕基本的“增删改查”展开,详细的程序介绍可以私聊我本人获取ppt和实验报告,仅供学习和参考,转载需标明出处。
以下是部分效果图
管理员密码默认为123456,后续可以在代码里更改管理员密码。
需要特别注意的是,目前程序仍存在一定的弊端,例如题目信息如果过长,就会影响到布局,建议不要录入题目信息或选项信息过长的题目,也可以根据具体需求,自行改到代码。
Part1:程序框架设计
程序框架设计上,我设计了三个类,其中两个类用来封装数据,一个类用来封装方法,如上所示图表,Problem类封装了试题的题号、题目、选项A、B、C、D、正确答案这些数据,Student类中我们有学生的用户名、账号、密码、成绩、答题时间这些成员,Manage类中封装了我们程序所需要的方法,程序整体结构分明,层次清晰,代码规范整齐。
其中,save_information方法和read_information方法之后我将着重讲解,log_in和student_login方法通过同样的底层逻辑实现,都是对循环遍历的运用来判断登录成功的条件是否满足,add_problem方法和del_problem、del_student方法是系统操作最常见的“增删查改”四大操作的“增和删”,通过input函数输入该输入的信息,将输入的信息整体打包成一个字典,字典特有的key值之后会帮助我们很好的提取所需要的数据,再将字典append到学生/试卷列表中,实现添加。而rank_student方法和analysis_student方法是对学生成绩的基本处理,其中涉及到利用sorted函数对列表实现快速排序,最后的test_begin先向函数传递学生姓名的参数,再循环遍历文件中的试题信息,来判断你的答案是否正确并计分,最后遍历文件中的学生信息来匹配函数接受到的学生姓名,将计分的成绩更新到学生的信息中,此外,还调用了time库来记录学生的答题时间信息。
test_begin方法的实现
Part2:文件读取和写入
存储文件的时候,由于我们只能向文件写入str类型的数据,而在程序中,我们文件里的数据是放在了一个字典嵌套的列表中的,为了方便我们读取数据,我们在写入数据时,每两个数据中我们写入一个逗号作为整个字符串的分隔符。
读取数据的时候,我们读取的初始数据是一个字符串,用split函数初步处理后,就变成了一个列表,但此时还没有满足我们所需要的字典嵌套列表,所以我们进一步将整个列表按照字典的需求分成一个个的字典,在放到一个新的列表中,此时的新列表就能满足我们的使用需求。以下的图示以学生信息的读取和写入为例。
文件读取的实现
文件写入的实现
为了进一步理解文件读取这一部分的实现,我们设计了以下的流程图来帮助我们更生动形象的理解数据从文件到我们所需要的要求所经历过的步骤。如下图所示。
数据的处理过程
Part3:GUI设计
在GUI设计方面,我们通过tkinter库来实现,tkinter是python的内置库是一套完整的GUI开发模块的组合或套件,这些模块共同提供了强大的跨平台GUI编程的功能,所有的源码文件位于Python安装目录中lib\tkinter文件夹。
tkinter与turtle类似,无需额外安装,使用起来非常方便。tkinter提供了很多控件和消息事件,可以很快入手,非常适合开发具有界面的轻量级应用程序。
图形化界面
在布局方面,我采用了place的布局方式,同时,在答题功能的图形化过程中,还引入了frame框架来实现滑块和文本框的联动,初步掌握了GUI的布局设计,了解到事件的处理、控件之间的命令的运行逻辑。
