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?
