Requisito previo: GUI de Python – tkinter
Python proporciona un marco GUI estándar Tkinter que se utiliza para desarrollar aplicaciones GUI rápidas y sencillas. Aquí desarrollaremos un cuestionario simple de opción múltiple en python con GUI. Crearemos un cuestionario de opción múltiple en Python con Tkinter. Primero, crearemos una biblioteca llamada Quiz en el directorio de su preferencia.

Pasos necesarios
1. Crearemos data.json para almacenar los datos
Los datos para el cuestionario se definen en data.json con datos JSON que son pares de nombre/valor y contienen una array de valores. Hemos definido datos de muestra para el cuestionario como se muestra a continuación:
{ "question": [ "Q1. What Indian city is the capital of two states?", "Q2. Which city is the capital of India?", "Q3. Smallest State of India?", "Q4. Where is Taj Mahal Located?" ], "answer": [ 1, 2, 3, 2 ], "options": [ ["Chandigarh", "Kolkata", "Delhi", "Bangalore" ], ["Jaipur", "Delhi", "Chennai", "Mumbai" ], ["Rajasthan", "Punjab", "Goa", "Bihar" ], ["Lucknow", "Agra", "Bhopal", "Delhi" ] ] }
2. Creando la GUI usando Tkinter en quiz.py
- Importando el módulo: tkinter y json
- Crear la ventana principal (contenedor) de la aplicación
- Agregar widgets para mostrar datos
- Añadir las funcionalidades al botón.
- Uso de los datos en el cuestionario
Nota: Tanto data.json como quiz.py se crearán en el mismo directorio que hemos definido anteriormente.
Ahora que hemos creado el archivo data.json para almacenar los datos, vamos a crear el archivo quiz.py que contendrá el programa para el cuestionario.
