Introducción a Python

Limpiar los registros

Los archivos de registro suelen contener marcas de tiempo que indican cuándo ocurrió el evento y niveles de registro (INFO, TRACE, ERROR). Tu tarea es limpiar esa información para que solo quede la parte importante.
log.txt contiene los registros sin limpiar.
El programa debe imprimir los registros limpios en la salida.
