I wrote the below code

    def _in_range(value):
        value = int(value)
        if (not (low <= value < high)):
            print_error((u'\n**    ERROR:    khmer    only    supports    %i    <=    %s    <    %i.\n' % (low, parameter_name, high)))
            sys.exit(1)
        else:
            return value
    return _in_range

What's a good function header?
 Here's a good function header?
