Este capítulo asume que estás familiarizado con los fundamentos de la programación orientada a objetos (POO) en Python: creación de clases, definición de métodos y herencia simple. En este capítulo ampliarás esos conocimientos.
Como con cualquier lenguaje orientado a objetos, es útil conocer lospatrones de diseño:solucionesreutilizablesa problemas comunes relacionados con clases y objetos. Se ha escrito mucho sobre patrones de diseño. Y aunque mucho de ello es aplicable a Python, tiende a aplicarse de forma diferente.
Esto se debe a que muchos libros y artículos sobre patrones de diseño están escritos para lenguajes como Java, C++ y C#. Pero Python, como lenguaje, es diferente. Su tipado dinámico, sus funciones de primera clase y otros añadidos hacen que los patrones de diseño "estándar" funcionen de forma diferente.
Así que vamos a aprender en qué consiste realmente la programación orientada a objetos de Python.
