Making .log files persistent

Question

I have a software which generates .log files, and the problem is that they are not persistent (each time the programs try to write an event it might rewrite over an past event which is not desirable)

Do you know a way in which I can write a python script for detecting when the program is opening a .log file in order to write something and make sure that he is not overwriting?

Thanks!

In Python, the logging package defaults to append

import logging

logging.basicConfig(
            filename=<out-path>, # to print stdout to file
            format=line_format,
            level=logging.DEBUG)

Then, you can write to the logfile by

logging.info(.)

or another one of logging's levels.
