New submission from Clint Olsen <[email protected]>:
When I run the following program, I expect args.run to be 'foo' if no argument
is specified on the command-line.
parser = argparse.ArgumentParser()
parser.add_argument('foo', default='bar')
args = parser.parse_args()
$ ./test
usage: test [-h] foo
test: error: the following arguments are required: foo
However if I specify nargs='*' this error goes away.
Maybe I'm missing something obvious, but this seems non-intuitive to me.
