Cree una hoja de marcas de la GUI de Python. Donde se otorgan créditos de cada materia, ingrese las calificaciones obtenidas en cada materia y haga clic en Enviar. Los créditos por asignatura, los créditos totales y el SGPA se muestran después de calcularse automáticamente. Use Tkinter para crear la interfaz GUI.
Consulte los siguientes artículos para hacerse una idea de los conceptos básicos de tkinter y Python.
Python ofrece múltiples opciones para desarrollar una GUI (interfaz gráfica de usuario). De todos los métodos GUI, Tkinter es el método más utilizado. Es una interfaz estándar de Python para el kit de herramientas Tk GUI que se envía con Python. Python con Tkinter genera la forma más rápida y sencilla de crear aplicaciones GUI. Crear una GUI usando Tkinter es una tarea fácil.
Para crear un Tkinter:
- Importando el módulo – Tkinter
- Crear la ventana principal (contenedor)
- Agregue cualquier cantidad de widgets a la ventana principal
- Aplique el evento Trigger en los widgets.
Así es como se vería la GUI:
Vamos a crear una hoja de calificaciones simple basada en GUI usando el módulo Python Tkinter, que puede crear una hoja de calificaciones basada en las calificaciones ingresadas por materia.
A continuación se muestra la implementación:

# GUI mark sheet using tkinter
