Python|使用 Tkinter 创建 GUI Marksheet
创建一个Python GUI 标记表。在给出每个科目的学分的情况下，输入在每个科目中获得的成绩，然后单击提交。每个科目的学分、总学分以及SGPA在自动计算后显示。使用 Tkinter 创建 GUI 界面。

Python为开发 GUI（图形用户界面）提供了多种选择。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。带有 Tkinter 的Python输出创建 GUI 应用程序的最快和最简单的方法。使用 Tkinter 创建 GUI 是一项简单的任务。
创建 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
- 在小部件上应用事件触发器。
这是 GUI 的外观：
让我们使用Python Tkinter 模块创建一个基于 GUI 的简单标记表，该模块可以根据每个主题输入的标记创建一个标记表。
下面是实现：
Python3
# Python program to create a
# GUI mark sheet using tkinter
# Import tkinter as tk
import tkinter as tk
# creating a new tkinter window
master = tk.Tk()
# assigning a title
master.title("MARKSHEET")
# specifying geometry for window size
master.geometry("700x250")
# declaring objects for entering data
