New issue 69 by AndrewAlex: Request: Method for prompting for arguments let
out
http://code.google.com/p/argparse/issues/detail?id=69

For programs requiring a large number of arguments I make my them optional
and then do something like the code below. This (or a more integrated
implementation) may be useful for argparse.

args = parser.parse_args()
prompt_for_arg(args.name, "Name: ")
prompt_for_arg(args.company, "Company: ")
prompt_for_arg(args.homedir, "Users Home Directory: ")

def prompt_for_arg(argfield, prompt):
if argfield is not None:
return False
try:
argfield = input(prompt)
if len(argfield) > 0:
return True
except:
pass
print("Aborted")
sys.exit()

I was too rough in stripping out the code above, the function above does
not work.
This one should

def prompt_for_arg(arg, field, prompt):
if getattr(arg, field) is not None:
return False
try:
r = input(prompt)
if len(r) > 0:
setattr(arg, field, r)

Closing as WontFix, mainly because I didn't see any additional community
requests for it. Feel free to open a new issue at bugs.python.org
(argparse's new home) if you know of others asking for similar behavior.
