254 * The program is written so as to display something when ``--verbosity`` is
259   used, the relevant variable, in this case :attr:`args.verbosity`, is
265 * When using the ``--verbosity`` option, one must also specify some value,
268 The above example accepts arbitrary integer values for ``--verbosity``, but for
274    parser.add_argument("--verbose", help="increase output verbosity",
278        print("verbosity turned on")
285    verbosity turned on
294      --verbose   increase output verbosity
320    parser.add_argument("-v", "--verbose", help="increase output verbosity",
324        print("verbosity turned on")
331    verbosity turned on
337      -v, --verbose  increase output verbosity
352                        help="increase output verbosity")
379 multiple verbosity values, and actually get to use them::
385    parser.add_argument("-v", "--verbosity", type=int,
386                        help="increase output verbosity")
389    if args.verbosity == 2:
391    elif args.verbosity == 1:
403    usage: prog.py [-h] [-v VERBOSITY] square
404    prog.py: error: argument -v/--verbosity: expected one argument
413 Let's fix it by restricting the values the ``--verbosity`` option can accept::
419    parser.add_argument("-v", "--verbosity", type=int, choices=[0, 1, 2],
420                        help="increase output verbosity")
423    if args.verbosity == 2:
425    elif args.verbosity == 1:
436    prog.py: error: argument -v/--verbosity: invalid choice: 3 (choose from 0, 1, 2)
445      -v {0,1,2}, --verbosity {0,1,2}
446                            increase output verbosity
451 Now, let's use a different approach of playing with verbosity, which is pretty
453 verbosity argument (check the output of ``python --help``)::
459    parser.add_argument("-v", "--verbosity", action="count",
460                        help="increase output verbosity")
463    if args.verbosity == 2:
465    elif args.verbosity == 1:
481    $ python3 prog.py 4 --verbosity --verbosity
494      -v, --verbosity  increase output verbosity
525    parser.add_argument("-v", "--verbosity", action="count",
526                        help="increase output verbosity")
531    if args.verbosity >= 2:
533    elif args.verbosity >= 1:
549        if args.verbosity >= 2:
564    parser.add_argument("-v", "--verbosity", action="count", default=0,
565                        help="increase output verbosity")
568    if args.verbosity >= 2:
570    elif args.verbosity >= 1:
605    parser.add_argument("-v", "--verbosity", action="count", default=0)
608    if args.verbosity >= 2:
610    elif args.verbosity >= 1:
631      -v, --verbosity
636 Notice that so far we've been using verbosity level to *change* the text
637 that gets displayed. The following example instead uses verbosity level
644    parser.add_argument("-v", "--verbosity", action="count", default=0)
647    if args.verbosity >= 2:
649    if args.verbosity >= 1:
