如何将maya节点层次存储到python字典中

import maya.cmds as cmds

def get_node_hierarchy(node):
    # 获取节点的子节点
    children = cmds.listRelatives(node, children=True) or []
    
    # 创建字典来存储节点信息
    node_dict = {
        "name": node,
        "children": []
    }
    
    # 递归遍历子节点
    for child in children:
        child_dict = get_node_hierarchy(child)
        node_dict["children"].append(child_dict)
    
    return node_dict

# 获取场景根节点
root_nodes = cmds.ls(assemblies=True)
if len(root_nodes) > 0:
    root_node = root_nodes[0]
    node_hierarchy = get_node_hierarchy(root_node)
    print(node_hierarchy)
