Python使用Tkinter创建GUI标记表

创建一个python GUI标记表。在给出每个学科的学分的地方, 输入在每个学科中获得的成绩, 然后单击提交。在自动计算后, 将显示每个科目的学分, 总学分以及SGPA。使用tkinter创建GUI界面。

请参阅以下文章, 以了解有关tkinter和Python的基础知识。 Tkinter简介Python基础

Python提供了多种开发GUI(图形用户界面)的选项。在所有的GUI方法中, Tkinter是最常用的方法。它是Python随附的Tk GUI工具包的标准Python接口。 Python与Tkinter输出最快和最简单的方式来创建GUI应用程序。使用创建GUITkinter是一件容易的事。
创建一个tkinter：

导入模块– tkinter
创建主窗口(容器)
将任意数量的小部件添加到主窗口
将事件触发器应用于小部件。

让我们使用Python创建基于GUI的简单标记表Tkinter模块, 可以基于每个主题输入的分数创建分数表。
下面是实现：
