+#16 - EXPRESIONES REGULARES
+"""
+ * EJERCICIO:
+ * Utilizando tu lenguaje, explora el concepto de expresiones regulares,
+ * creando una que sea capaz de encontrar y extraer todos los números
+ * de un texto.
+ *
+ * DIFICULTAD EXTRA (opcional):
+ * Crea 3 expresiones regulares (a tu criterio) capaces de:
+ * - Validar un email.
+ * - Validar un número de teléfono.
+ * - Validar una url.
