Re: Searching for a file

To get a list of files in a given directory one can use glob.glob and os.path.isfile >>> from os.path import isfile >>> from glob import glob >>> files_in_var_tmp = [f for f in glob('/var/tmp/*') if isfile(f) ] For several directories iterate over the dirs and add the resulting list of files. >>

Hello Michael, thank you for your important question. On GNU/Linux (and maybe for POSIX?) systems there is a standard about it. Look for $XDG_CONFIG_HOME. To drive it further, you might distinguish between config data (related and
