* El día 128 del año celebramos en la comunidad el "Hola Mundo day" | ||
* Vamos a hacer "web scraping" sobre su sitio web: https://holamundo.day | ||
* | ||
* Crea un programa que se conecte a la web del evento e imprima únicamente la agenda de eventos | ||
* del día 8. Mostrando hora e información de cada uno. | ||
* Ejemplo: "16:00 | Bienvenida" | ||
* | ||
* Se permite utilizar librerías que nos faciliten esta tarea. | ||
* | ||
* | ||
* | ||
* HECHO POR PANCRATZIA - 07/09/2023 | ||
