The codes in test.py are:
---------
import argparse
parser = argparse.ArgumentParser()
parser.add_argument('--foo', nargs='?', help='foo help')
parser.add_argument('--goo', nargs=1, help='goo help')
args = parser.parse_args()
print(args.foo, args.goo)
---------
But I get the following result:
---------
D:\Works\Python>py test.py -h
usage: test.py [-h] [--foo [FOO]] [--goo GOO]
optional arguments:
-h, --help show this help message and exit
--foo [FOO] foo help
--goo GOO goo help
D:\Works\Python>py test.py --foo 1 --goo 2
1 ['2']
---------
It seems to me that the help message should be:
usage: test.py [-h] [--foo FOO] [--goo [GOO]]
Do I had missed something?
