对于这个88275023问题，我制定了（但未发布）此Formatter类。变化快到尽头了
class CustomFormatter(argparse.HelpFormatter): def _format_action_invocation(self, action): if not action.option_strings: metavar, = self._metavar_formatter(action, action.dest)(1) return metavar else: parts = [] # if the Optional doesn't take a value, format is: # -s, --long if action.nargs == 0: parts.extend(action.option_strings) # if the Optional takes a value, format is: # -s ARGS, --long ARGS # change to # -s, --long ARGS else: default = action.dest.upper() args_string = self._format_args(action, default) for option_string in action.option_strings: #parts.append('%s %s' % (option_string, args_string)) parts.append('%s' % option_string) parts[-1] += ' %s'%args_string return ', '.join(parts)
