New submission from Doug Hellmann <doug.hellm...@gmail.com>: Most of the argparse type converters handle exceptions with a single line error message explaining the problem. For example, if an argument -i is declared as an int, but the value given ('a') cannot be converted to an int, the message is something like "argument -i: invalid int value: 'a'".
On the other hand, FileType raises an IOError, which isn't being caught and converted to the simpler error message. Instead, a full traceback is printed. To be consistent, the IOError should be trapped and a single error message printed. ---------- components: Library (Lib) files: argparse_filetype_error.py messages: 112798 nosy: doughellmann priority: normal severity: normal status: open title: argparse FileType raises ugly exception for missing file versions: Python 2.7, Python 3.2 Added file: http://bugs.python.org/file18380/argparse_filetype_error.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9509> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
