paul j3 added the comment: Another failure case:
parser.add_argument('--int', type=int, choices=[10,15,25]) '--int 15` puts 'int=15' in the Namespace. '--int 2' puts 'int=2' in the Namespace, because it matches the 'str(25)'. '--int 1' raises an error in the ambiguity error formatting code: 'choices': ', '.join(ac)} This last error could be corrected with: 'choices': ', '.join(map(repr, ac)) ================= The initial message for this issue stated: So that this feature is not foisted on every programmer that uses argparse it could be made an option to the ArgumentParser class with the (possible) additional refinement of specifying a minimum number of characters for the abbreviations. That was ignored in the subsequent discussion and patches. Other Choices issues http://bugs.python.org/issue16468 - argparse only supports iterable choices http://bugs.python.org/issue16418 - long choices http://bugs.python.org/issue16977 - choices='abc' case I recommend closing this issue, and depend on aliases for subparsers abbreviations. The interaction with 'choices' is just too complicated to handle as proposed here. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12713> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
