有没有比使用嵌套到最大深度的map语句更好的遍历未知深度对象的方法？

def traverse(obj):
    if isinstance(obj, dict):
        for key, value in obj.items():
            if isinstance(value, (dict, list)):
                traverse(value)
            else:
                # 处理键值对
                print(key, value)
    elif isinstance(obj, list):
        for item in obj:
            if isinstance(item, (dict, list)):
                traverse(item)
            else:
                # 处理列表元素
                print(item)
    else:
        # 处理其他类型的对象
        print(obj)

def traverse(obj):
    stack = [(obj, '')]
    while stack:
        item, prefix = stack.pop()
        if isinstance(item, dict):
            for key, value in item.items():
                if isinstance(value, (dict, list)):
                    stack.append((value, prefix + key + '.'))
                else:
                    # 处理键值对
                    print(prefix + key, value)
        elif isinstance(item, list):
            for i, value in enumerate(item):
                if isinstance(value, (dict, list)):
                    stack.append((value, prefix + str(i) + '.'))
                else:
                    # 处理列表元素
                    print(prefix + str(i), value)
        else:
            # 处理其他类型的对象
            print(prefix[:-1], item)
