That will fail on Linux too, if the current working directory is somewhere
that the user doesn't have write permission.
The *right* way to do this is:
- allow the user to optionally specify a log file location;
- if they don't, set a sensible default according to the platform, e.g.:
# untested
DEFAULTS = {
'nt': '...',
'linux': '...',
'macos': '...',
}
location = DEFAULTS.get(sys.platform, 'somewhere else')
Read the docs for the list of possible values for sys.platform.
Generally, for system tools, you should write to a system-wide location. On
Linux, that might be /var/log/FILENAME. But that's not generally writable
by unprivileged users, so you might want to log directly in the user's home
directory:
os.path.expanduser('~/FILENAME')
which ought to do the right thing on Windows, POSIX systems (including Linux
and OS X).
