I think you can change the comment to just 'ignore files' since it will ignore
any file, no matter if it's a system file or a normal one.

Our Python style guide limits lines to 79 characters (following PEP8, which is
more or less of a universal standard). You can reformat this line like this, to
make it compliant:

        return attribute & (win32con.FILE_ATTRIBUTE_HIDDEN |
                            win32con.FILE_ATTRIBUTE_SYSTEM)
