New submission from Juraj Variny:
Example:
parser.add_argument("-p","--port", help="Listening port", type=int,
choices=range(1, 65535),default=8007,required = False)
generates this usage text:
usage: agent.py [-h]
[-p
{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,
<...snip...>
,65522,65523,65524,65525,65526,65527,65528,65529,65530,65531,65532,65533,65534}]
optional arguments:
-h, --help show this help message and exit
-p {1,2,3,4,5,6,7,8,9,10,11,12,13,14, <...snip...>
,65525,65526,65527,65528,65529,65530,65531,65532,65533,65534}
