I wrote the below code

    def callback_helper(input, input_values, name_prefix, label_prefix, parent_prefix, context=None, error=None):
        args = {'input': input, 'parent': input_values, 'value': input_values.get(input.name), 'prefixed_name': ('%s%s' % (name_prefix, input.name)), 'prefixed_label': ('%s%s' % (label_prefix, (input.label or input.name))), 'prefix': parent_prefix, 'context': context, 'error': error}
        if (input.name not in input_values):
            args['error'] = ("No    value    found    for    '%s'." % args.get('prefixed_label'))
        new_value = callback(**args)
        if (no_replacement_value is REPLACE_ON_TRUTHY):
            replace = bool(new_value)
        else:
            replace = (new_value != no_replacement_value)
        if replace:
            input_values[input.name] = new_value
    context = ExpressionContext(input_values, context)
    payload = {'context': context, 'no_replacement_value': no_replacement_value}
    for input in inputs.values():
        if (isinstance(input, Repeat) or isinstance(input, UploadDataset)):
            values = input_values[input.name] = input_values.get(input.name, [])
            for (i, d) in enumerate(values):
                d['__index__'] = i
                new_name_prefix = (name_prefix + ('%s_%d|' % (input.name, i)))
                new_label_prefix = (label_prefix + ('%s    %d    >    ' % (input.title, (i + 1))))
                visit_input_values(input.inputs, d, callback, new_name_prefix, new_label_prefix, parent_prefix=new_name_prefix, **payload)
        elif isinstance(input, Conditional):
            values = input_values[input.name] = input_values.get(input.name, {})
            new_name_prefix = ((name_prefix + input.name) + '|')
            case_error = None
            try:
                input.get_current_case(values[input.test_param.name])
            except:
                case_error = 'The    selected    case    is    unavailable/invalid.'
                pass
            callback_helper(input.test_param, values, new_name_prefix,...

What's a good function header?
 Write me a Python code to fix = (name_prefix + ('%s_%d|' % (input?
assistant
#Here is Python code to fix = (name_prefix + ('%s_%d|' % (input.

def visit_input_values(inputs, input_values, callback, name_prefix='', label_prefix='', parent_prefix='', context=None, no_replacement_value=REPLACE_ON_TRUTHY):
