Suppose I have the following argparse snippet:
diags.cmdln_parser.add_argument( '--scan-time', action = 'store', nargs = '?', type = int, default = 5, help = "Wait SCAN-TIME seconds between status checks.")
Currently, --help returns:
usage: connection_check.py [-h] [--version] [--scan-time [SCAN_TIME]] Test the reliability/uptime of a connection. optional arguments: -h, --help show this help message and exit --version show program's version number and exit --scan-time [SCAN_TIME] Wait SCAN-TIME seconds between status checks.
I would prefer something like:
--scan-time [SCAN_TIME] Wait SCAN-TIME seconds between status checks. (Default = 5)
Peeking at the help formatter code revealed limited options. Is there a clever way to get argparse to print the default value for --scan-time in a similar fashion, or should I just subclass the help formatter?
