En el capítulo anterior, comenzamos a explorar en profundidad los tipos de objeto fundamentales de Python estudiando los números de Python y sus operaciones. Reanudaremos nuestro recorrido por los tipos de objeto en el próximo capítulo, pero antes de seguir adelante, es importante que conozcas lo que puede ser la idea más fundamental de la programación en Python y que, sin duda, es la base de gran parte de la concisión y flexibilidad del lenguaje Python: el tipado dinámico y el polimorfismo que implica.
Como verás aquí y a lo largo de este libro, en Python no necesitamos declarar los tipos específicos de los objetos que utilizan nuestros scripts. De hecho, la mayoría de los programas no deberían preocuparse por los tipos específicos, apropósito. Al evitar las restricciones de este modo, el código funciona de forma natural en muchos contextos y, a menudo, más de lo esperado. Dado que la tipificación dinámica es la raíz de esta flexibilidad, y también un posible escollo para los recién llegados, hagamos un breve viaje lateral para explorar el modelo aquí. Al final del viaje, también haremos una breve parada en la paradoja de la sugerencia de tipo, para aprender por qué deberías evitarla.
