python使用tkinter实现学生信息管理系统(下)

前言:

原本我是不打算写下篇的,原因我也说了,没什么用纯粹是写着玩的,而且隔了好长时间了我也没什么印象了想要接上比较费时费力,但是我发现一件很神奇的事情,就是我觉得有用的文章没有太多人看,而这种花里胡哨的文章你们却很感兴趣,导致好多人问我要下篇,我想了想反正放假了也没什么事情,那就应广大网友的要求就把他补全吧(哈哈哈,想打我吗?)。

正文:

我们接着上一篇的内容继续做拓展,上篇我们实现了登录,显示,关键字搜索的操作,这一篇我们来把增删改查补全,再加上一个保存的功能。至此一个简单的学生信息管理系统就都搞定了。

老规矩先上图:

用户名和密码在最上方,可自行修改:

#先定义几个可能用到的常量
user_name = "kkyyds" #凯子哥永远的神,哈哈
password = "123456"

明细窗体:

增加和修改我们需要一个新的窗口进行操作,为了提高代码的可读性,我们新开一个py文件,文件名就叫明细窗口。

主界面:

主界面要连接明细窗口,使用import导入明细窗口,在进行函数的书写。为了你们能够看的清晰直观,我就不进行代码的拆分了,直接全部放出,防止有的地方你们连接不上。
