61 | <div class="verbatim"><pre> | |
62 | from optparse import OptionParser | |
63 | [...] | |
64 | def main(): | |
65 | usage = "usage: %prog [options] arg" | |
66 | parser = OptionParser(usage) | |
67 | parser.add_option("-f", "--file", dest="filename", | |
68 | help="read data from FILENAME") | |
69 | parser.add_option("-v", "--verbose", | |
70 | action="store_true", dest="verbose") | |
71 | parser.add_option("-q", "--quiet", | |
72 | action="store_false", dest="verbose") | |
73 | [...] | |
74 | (options, args) = parser.parse_args() | |
75 | if len(args) != 1: | |
76 | parser.error("incorrect number of arguments") | |
77 | if options.verbose: | |
78 | print "reading %s..." % options.filename | |
79 | [...] | |
