Here's what optparse-based scripts typically look like:
from optparse import OptionParser
[...]
def main():
usage = "usage: \%prog [-f] [-v] [-q] firstarg secondarg"
parser = OptionParser(usage)
parser.add_option("-f", "--file", type="string", dest="filename",
help="read data from FILENAME")
parser.add_option("-v", "--verbose",
action="store_true", dest="verbose")
parser.add_option("-q", "--quiet",
action="store_false", dest="verbose")
(options, args) = parser.parse_args()
if len(args) != 1:
parser.error("incorrect number of arguments")
if options.verbose:
print "reading \%s..." \% options.filename
[... go to work ...]
if __name__ == "__main__":
main()
