Introduzione a Python

Pulire i log

I file di log solitamente contengono timestamp che indicano quando si è verificato un evento e livelli di log (INFO, TRACE, ERROR). Il tuo compito è ripulire queste informazioni in modo che resti solo la parte importante.
Il file log.txt contiene i log da pulire.
Il programma dovrebbe stampare in output i log puliti.
