Requisitos previos : Tkinter
Tkinter es una biblioteca de Python muy famosa para crear una aplicación de escritorio para Windows y sistemas operativos basados en UNIX. La idea aquí es generar un código python para construir una aplicación de noticias con Tkinter. Puede obtener fácilmente una clave API de newsapi.org .
