Pero incluso los scripts pequeños pueden beneficiarse.
Python proporciona registro a través del módulo logging. En mi opinión, este módulo es una de las partes técnicamente más impresionantes de la biblioteca estándar de Python. Está bien diseñado, es flexible, seguro para hilos y muy potente. También es complejo, con muchas partes móviles, lo que hace difícil aprenderlo bien.
