After re-reading the documentation, I think the behaviour for subparsers is not specified: It is not specified, whether a subparser is required to be present or not. Attached stripped down version of the cdist code to a bare minimum (subparse.py) which shows the problem more clear: % python3 -V Python 3.2.3 % python3 ~/subparse.py usage: subparse.py [-h] [-V] {banner} ... subparse.py: error: too few arguments versus [15:44] brief:~% python3 -V Python 3.3.0 [15:46] brief:~% python3 subparse.py Traceback (most recent call last): File "subparse.py", line 31, in <module> commandline() File "subparse.py", line 25, in commandline args.func(args) AttributeError: 'Namespace' object has no attribute 'func' ---------- Added file: http://bugs.python.org/file27694/subparse.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16308> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
