我有一个将值添加到OrderedDict的循环：
Table SyTree：
id |名称|如此可见| parent_id
1 |目录| [null] |真| 0
362 |衣服10 |真实| 1
54 |盘子| 20 |真实| 1
.......
2 | new_year_pr | 160 |真实| 1
340 | new_year_package | 0 |真实| 2
338 | new_year_off | 0 |真实| 2
子类别的即，parent_id与需要挂钩的类别的id匹配。我为地图（站点树）全部完成]
qs_catalog_items = SyTree.objects.filter(visible=True).order_by('parent_id', 'so')
od = OrderedDict()
for obj in qs_catalog_items:
if obj.parent_id in od:
od[obj.parent_id].items.append(obj)
else:
obj.items = []
od[obj.id] = obj
[请告诉我如何迭代（并打印）它，以使每个OD元素中都有一个list类型的属性。
