Question

I have log files ( named in the format YYMMDD ) and I\'d like to create a script that get only important information from the files ( like the lines that contains \"O:NVS:V

Answer 1

You'll need to know how to loop over files in a directory, regular expressions to make sure your log file format matches to file you are looping over, how to open a file, how to loop over the lines in the open file, and how to check if one of those lines contains what you are looking for.

And here some code to get you started.

with open("log.log" 'r') as f:
    for line in f:
        if "O:NVS:VOICE" in line:
            print line
