Para que la codificación de clases sea más fácil de asimilar, comenzaremos nuestra exploración detallada de la POO echando un primer vistazo a algunas clases básicas en acción en este capítulo. Ampliaremos los detalles introducidos aquí en capítulos posteriores de esta parte del libro, pero en su forma básica, las clases de Python son fáciles de entender.
