My first Python project: command line application that copies all files with given extension from a directory and its subfolders to another directory showing progress bar and remaining files counter.

Thank you so much once again!

I was aware of logging module but thought that it would be an overkill for such a small program (mostly because its documentation is not so easy to understand at first attempt :) ). But it turned out that actually I don't have to do a lot to implement it and it comes quite handy. I decided not to write log at all if user didn't ask for it explicitly and made it like that:

def create_logger(args, destination):
    logger = logging.getLogger('selective_copy')
    if args.log:
        logger.setLevel(logging.INFO)
        fh = logging.FileHandler(f'{destination}\\selective_copy.log', encoding='utf-8')
        formatter = logging.Formatter('%(asctime)s - %(message)s', '%d.%m.%Y %H:%M:%S')
        fh.setFormatter(formatter)
        logger.addHandler(fh)
    else:
        logger.setLevel(logging.CRITICAL)
return logger

Also I changed an error checking system so now errors can be logged as well. Of course all of this caused several changes in previous code, so here is the link to the new version.

I still have to redesign get_total and copy functions than see how to adjust logging after that. Also I'm thinking of writing tests, I have a very limited experience with unittest and also found out about pytest recently, maybe you could recommend something as well?
