如何解码一个带有嵌套数组的字典？

def decode_nested_dict(dictionary):
    result = {}
    for key, value in dictionary.items():
        if isinstance(value, dict):
            result[key] = decode_nested_dict(value)
        elif isinstance(value, list):
            result[key] = decode_nested_list(value)
        else:
            result[key] = value
    return result

def decode_nested_list(lst):
    result = []
    for item in lst:
        if isinstance(item, dict):
            result.append(decode_nested_dict(item))
        elif isinstance(item, list):
            result.append(decode_nested_list(item))
        else:
            result.append(item)
    return result
