Which style convention is it referring to? Should these really be all
caps?
I think pylint is expecting that any variables declared outside of a
function should be constants with special meanings (similar to #define or
enum values in c). So, I guess to get rid of that message you should do
something like this:
<code>
def main(args=None):
if args is None:
args = sys.argv
parser = optparse.OptionParser(usage='usage: %prog [OPTIONS]')
parser.add_option('-c', '--config',
action='store',
type='string',
dest='configFilename',
help='config file containing defaults')
(options, args) = parser.parse_args(args)
if "__main__" == __name__:
sys.exit(main())
</code>
Here is an article by GvR that goes over main functions in python:
http://www.artima.com/weblogs/viewpost.jsp?thread=4829. You didn't really
ask for it, but I think it is good reading. His examples all use getopt
though, instead of optparse. I have come up with my own (probably overkill
for 99% of python scripts) template that uses optparse. If you really want
to see it let me know and I will send it to you.
