[issue14149] argparse: Document how to use argument names that are not Python identifiers

[Dan Arad]

Dan Arad  added the comment:

Hi everyone!

I thought to take this issue up by updating the documentation. Is this still 
relevant?

If so I think the best place to add the documentation is in the "name or flags" 
section, where people will go looking first. I think to add both the metavar 
and the vars solutions discussed below.

#11076 was closed as a duplicate of #8982 which was closed as fixed so can this 
also be closed as a duplicate?

 I don’t understand, can you rephrase?

Sorry, I mean making Namespace subscriptable.  eg:

 v = argparse.Namespace(abc = 123)
 v
Namespace(abc=123)
 v.abc
123
 v['abc']
Traceback (most recent call last):
  File stdin, line 1, in module
TypeError: 'Namespace' object is not subscriptable

 add_argument('foo_bar', metavar='foo-bar', ...)

This works. Thanks!

Cheers,
Joe

 making Namespace subscriptable

This has been discussed before - see issue 11076. I prefer to keep Namespace as 
simple as possible. For subscripting, just use the standard Python idiom of 
vars as suggested in the docs:

http://docs.python.org/library/argparse.html#the-namespace-object
