Message334065
When argparse is configured with an option that takes arguments, then the script is invoked with the switch but no arguments, a nonsensical exception is raised during gettext processing.
In the 3.7.1 source, the error is at line 2077 of argparse.py, where 'action.nargs' is not an integer as expected by 'ngettext', but one of None, '*' or '?':
default = ngettext('expected %s argument',
'expected %s arguments',
action.nargs) % action.nargs
msg = nargs_errors.get(action.nargs, default)
Fix should be pretty trivial, swap the two lines and if 'get' produces None, only then compute the default.
