遍历和修改类似于dict结构的树状列表

def traverse_and_modify(tree):
    if isinstance(tree, dict):
        for key, value in tree.items():
            # 遍历键值对
            print("Key:", key)
            print("Value:", value)
            
            # 递归遍历子节点
            traverse_and_modify(value)
    elif isinstance(tree, list):
        for item in tree:
            # 递归遍历子节点
            traverse_and_modify(item)
    else:
        # 修改节点的值
        # 这里可以根据实际需求进行修改操作
        tree = "Modified"
        print("Modified Value:", tree)

# 示例树状列表
tree = {
    "key1": "value1",
    "key2": [
        {
            "key3": "value3",
            "key4": "value4"
        },
        {
            "key5": "value5"
        }
    ]
}
